2.6.[45]-.*: weird behavior

2.6.[45]-.*: weird behavior

[R. J. Wysocki]

Hi,

For quite some time I've been observing strange keyboard problems with the 
kernels 2.6.4 and above.  Namely, in a GUI, the keyboard (which is a PS/2) 
sometimes seems to get "locked" for some time (usually for a couple of 
seconds) even if there's no any process running in the background (of course 
there are some processes in the background but they are all sleeping).  By 
saying "locked" I mean that the kernel does not seem to accept any keyboard 
input whatsoever at that time, but after the kayboard gets "unclocked" it 
properly passes all of the characters typed in the meantime to applications.

Moreover, it often takes more time to "unlock" the keyboard (up to 30 sec. or 
so), in which case I can speed up the proccess by switchig windows with a 
mouse (usually it is sufficient to switch once to another window, but 
sometimes more window switching is necessary).

Some days ago I noticed that similar problem occured for example when I tried 
to unpack the kernel source: the tar process had apparently been suspended 
for several times for up to 10 sec., so it took more than approx. 3 min. to 
unpack the source (usually it takes no more than 30 sec.).  There were not 
any processes running in the background, though.

I noticed that this happened after updatedb had finished so I tried to 
recreate this by running updatedb once again and than unpacking the kernel 
once again and the problem reappeared.  I'd run top before and I found that 
the CPUs were spending 90+ percent of the time on IO-wait (the system is a 
dual AMD64 w/ NUMA w/o kernel preemption).  Strange.

I thought it was accidental (the kernel was 2.6.5-rc3-mm2), but yesterday I 
noticed that the keyboard "locking" occured even more often after I had 
installed the 2.6.5-rc3-mm4 kernel (it happened after the machine had been - 
seemingly - idle for some time).  I ran top and that's what it showed me:

top - 23:14:39 up  3:21,  1 user,  load average: 1.24, 1.12, 1.05
Tasks: 111 total,   1 running, 110 sleeping,   0 stopped,   0 zombie
Cpu(s):   0.5% user,   0.0% system,   0.0% nice,  50.0% idle,  49.5% IO-wait
Mem:   1030060k total,  1000820k used,    29240k free,    18724k buffers
Swap:  1050608k total,     3520k used,  1047088k free,    50168k cached

and it had been showing similar things for a minute or so, which is a kind of 
weird, IMHO.  I mean, the only running process was the top itself, so I don't 
get the 49.5% IO-wait.

Then I thought it was a NUMA-related issue but today I had the "keyboard 
locking problem" on a Celeron (Coppermine)-based laptop running the 2.6.5-rc3 
with exactly the same symptoms (apparantly, the kernel stopped accepting the 
keyboard input or at least passing it to applications - I couldn't even 
switch from X to a console - and then, when I closed some windows with a 
mouse preparing the system for reboot, the keyboard got "unlocked" and it 
started to work as usual).  So, there are two different (though a bit 
similar) architectures affected, it seems.

Now, can you please tell me what may cause such a behavior?  I really would 
like to narrow it, so please tell me what I can do for this purpose (I've no 
idea whatsoever).

Yours,
Rafael

Hi,

Maybe you should make profile of the running kernel on both configurations 
to find what functions are called most often?

Can you attach config files for both the AMD64 and the laptop?

And can you reproduce this problem with 2.6.2-rc2-mm? or 2.6.2-mm? 
kernels? They are working for me and my friend well on all machines (with 
some minor issues) while >=2.6.4-mm? are broken on nearly all 
configurations (because of different, often unrelated reasons).


regards

The config for the laptop is attached, the other one must wait.  If you think 
of what they have in common, there's not much.

No, everything seems to be OK up to the 2.6.4-rc-something (roughly, the 
problem appeared in the 2.6.4 for the first time).

There are some issues with the 2.6.4-and-above kernels but I've managed to get 
almost all of them running anyway.

Ok, some questions to that config file. Why do you have:
- scsi emulation
- scsi
- both generic ide options
- large block devices (2TB)?

Can you post:
- distro name and version
- dmesg or log at the end of testing - better after such kb lock if you 
can reproduce, maybe after some stressing to see if any unnormal messages 
appeared
- lspci -v
- lsmod
- mount
- hdparm hdparm -iIvtT for all drives
- some files from /proc describing configuration if you think they are 
important.

Does any process sleep in D state in ps output all the time or bechaves 
strangely? If so, maybe you should find and apply the patch for kernel 
stack for each process in /proc (it was included in wolk for example) and 
check what kernel function is causing the waits (for example I found some 
usb problems causing D state lock of processes using some usb ioctls).

If it all does not help, maybe you should compile kernel with all debug 
and kernel hacking options to see if some driver does not lock the kernel 
and sleep or something like that, or possibly try to find what changeset 
between 2.6.3 and 2.6.4 broke your setup :)


good luck

SCSI support is necessary for USB storage, the rest is just for fun. :-)

Well, I _really_ had not much time to track this.  If I'd had time, I'd 
probably have checked all these things already.  I don't think there are any 
unusual things about what you list, though.

Good idea, I can do that.

Well, the patch-2.6.4.bz2 is 2.2+M big.  That's _a_ _lot_ of changesets, so I 
don't think I can figure out this, unless I know which one could 
_potentially_ cause the effects that I observe.  Please, give me a hint, if 
you have any idea.

Re: 2.6.[45]-.*: weird behavior

Maybe you should check IRQ sharing with ps port (if it is ps keyboard). Is 
it different under >=2.6.4-mm than under other kernels?

And maybe you should add boot options to turn ACPI and other similar 
options off.

And what video card are you using? There were some problems with S3 and 
other cards / XFree86 implementations in the past. Maybe kernel change is 
just exposing the problemm, not producing it? What about starting X with 
vesa or other "generic" driver insead of driver for your card.

I tried hard to reproduce your problem on my Athlon 32 box with 
2.6.5-rc3-mm4 but with no luck. I have some problems with this kernel, as 
with other kernels past 2.6.4 (for example I cannot mount any non root non 
virtual fs :)), but not this kind of problem. If I remember good I had one 
keyboard lockup under X in last month, but this was on 2.6.2-rc2-mm? 
kernel (probalby) after exiting from game (aa) and keyboard did not 
unlock (but I didint wait 30 sec - I do not have enough amount of 
patience :)). This problem never happened again.

What are exact steps to reproduce your problem?

And maybe the common thing with these two configurations is the 
SMP<->preemprion. These two are very similar in producing problems and if 
I remember good you have preemtion enabled on the laptop. Can you 
reproduce the problem without it?

I also found the patch for kernel stack in proc - it is here:

  http://thebsh.namesys.com/snapshots/LATEST/extra/a_04-proc-stack.patch

there is also iowait-reason and sleep-stat patch in the same directory.

And maybe try to reproduce the problem with 2.6.5 without mm. People like 
to have reports about "stable" kernels :)


good luck

PS. I am compiling 2.6.5 too to check if it works better for me.

First, thanks for your help!  Unfortunately I had no time to dig into it 
further and I'm now using the 2.6.5 too without any problems so far.  Let's 
see if it happens again,
