Total kernel freeze under 2.6.1

Total kernel freeze under 2.6.1

[Neil Macvicar]

I mailled before on this problem, but received no replies (!). anyways, a 
recap of the problem is: When I leave my computer running and doing whatever, 
if I come back to it after ~ 1 hour (any shorter lengths of time and the 
freeze doesn't occur) and either move the mouse or type on the keyboard, the 
entire system will freeze. I can tell that it hasn't frozen up to this point 
as if I am in X, the clock is still ticking etc, or if I am in console mode, 
and compiling somthing, then text is whizzing by, or HDD is active.

Now, I've done a further bit of investigation, and tried pinging the box 
instead of keyboard/mouse input, and the ping will cause the box to freeze 
also.

Note that this freeze happens _no matter what_ is running. The result is the 
same in console mode, as well as X, with modules loaded, or without any 
modules loaded.

Whilst under 2.4.x, this problem never manifested itself.

My system consists of the following:

PII 450MHz CPU
Intel 440BX MoBo
WinTV PCI card
Nvidia GeForce 2 AGP card (moduled driver)
Ens1371 PCI audio card 
Promise PCI IDE controller
Linksys Wireless USB adapter (moduled driver)

Re: Total kernel freeze under 2.6.1

[Christian Unger]

Forewarning ... i ain't "qualified" ... heck i couldn't get my gfx card to 
work on 2.6 until yesterday (and i still don't know why that was).

ANYWAY

i got the same symptoms, and the reason it was doing it on my system was that 
in the config i was using in several places it referenced the wrong chipset. 
via instead of nforce2 type thing. 

>From memory it did this all over the place with regards to sound, hdd and 
memory. 
Check
Device Drivers - ATA/ATAPI/MFM/RLL
Character Devices - AGP Support
		  - i2c Support
Sound 

etc ...

I'm sorry if this is completely useless. But it was what was at fault here.
PS there could be others that i can't remember ... just check for the right 
chipset.

with kind regards,
  Christian Unger

Thanks alot ! The offending part was in the ALSA driver. It had selected Sound 
-> ALSA -> PCI -> Intel 18x0/MX440, SiS 7012; Ali 5455 ; NForce Audio; 
AMD768/8111 by default, which I missed when I built the kernel.

Even so, this ought not to hang the kernel ! I'm surprised there wasn't more 
interest in this from developers.. hangs are serious issues.
