Heavy suspend and io problems in 2.6.27-rc1-00156-g94ad374

Hello¡

I've some serious problems with this kernel on the ibm t60:

- wake up from suspend takes about 30 seconds
- i need to switch to console and back to see xorg screen again (before:
  only black)
- after wake up, I get disk input/output errors, no access to sda is
  possible

As I could not do any dumps I took photos of the dmesg output with my
camera and put them in high resolution to

   http://home.schottelius.org/~nico/unix/linux/kernel/2.6.27-rc1-00156-g94ad374/

Sincerly,

Nico

Can you test the fix in http://bugzilla.kernel.org/show_bug.cgi?id=11178, please?

Thanks,
Rafael

Hello Rafael!

I tested the patch and also linux-next-20080801:

   linux-next-20080801: does not wake up
   linux-next-20080801+patch: wakes up, console keeps on being black
      -> no xorg running, as it cannot be run due to synaptics bug
         (fixed in git, not in debian lenny packages)

So I was able to type "reboot" when running the patch, while I had to
force power-off on the main linux-next-tree.

I am back on 2.6.26-next-20080725, which suspends and wakes up fine.

Sincerly,

Nico

Hello again!

I retested it with linux-next + updates from its branches
(=2.6.27-rc1-next-20080804-denkbrett-03792-g1d2be1a)

with and without the patch.

The result is still the same as below.

No xorg is running, btw.

Sincerly,

Nico

ps: I am using this tree:

   http://unix.schottelius.org/cgi-bin/gitweb.cgi?p=foreign/linux-2.6;a=summary

   Which is linux-next-20080804 + merges from the listed branches.

Well, fine, but this is not exactly helpful.

Can you test the current Linus' tree with the patch from bug #11178, please?

Thanks,
Rafael

I am using 2.6.27-rc1-denkbrett-00555-g8f616cd-dirty now, latest fetch
from Linus' tree + the patch and the problem is the same: Wakeup works,
but screen keeps on being blank.

I am running next-20080725 now again, which works.

Sincerly,

Nico

Suspend issues on 2.6.27-rc2 (was: Heavy suspend and io problems in 2.6.27-rc1-00156-g94ad374)

[Nico Schottelius]

[-- Attachment #1: Type: text/plain, Size: 462 bytes --]

Hello!

The problem continues to exist:

I tested it on vanilla 2.6.27-rc2: Same problem, system does not wake up.

Did not test the proposed patch, because it did not restore the console
in any tested case yet, though it at least wakes the system up.

Sincerly,

Nico

x1400, using radeonhd (also from git)

It's a T60 lenovo thinkpad.

There also are models with Intel graphics, I think.

Anyway, the problem is related to either the graphics driver, or ACPI.

Please verify if any ACPI-related settings haven't changed in your .config
between the good kernel and the failing one.

Thanks,
Rafael

Just to let you know, I am having suspend issues as well,
(not kernel related),
ATI chipset, my situation maybe different, but you never know.
last week I was using xorg 7.1 with no issues,
now after an upgrade through debian sid
xorg 7.3(or whatever the number is), the system wakes up
to a black screen, then after around two or three minuetes
I regain my screen again. Could be xorg, or something else.
Maybe you are having the same issue.
