latest kernel update makes suspend to ram unusable
Last modified: 2008-11-25 15:38:19 UTC
Using the 2.6.25.16-0.1-pae kernel and ati-fglrxG01-kmp-pae-8.532_2.6.25.16_0.1-1.1 on an IBM Thinkpad T43 works with suspend-to-ram/resume like a charm. Installing the latest kernel security patch to version 2.6.25.18 breaks suspend to ram. The laptop does no longer resume when in suspend mode (not even the USB bus is reactivated, as the LED light on my USB mouse is not turned on again). The laptop simply blocks and does not react to anything. I need to hard power-off the machine.
Is this reproducible without ati binary module?
Yes. I set Driver "ati" in xorg.conf, made sure lsmod does not show fglrx and tried again. Same result.
Hmm, that's duplicate of vanilla regression, and we even know which patch causes that IIRC... ...yes... commit ffa4da2a25bb4ac08f710ac99827baf48a8f8d57 Author: Thomas Gleixner <tglx@linutronix.de> Date: Wed Sep 3 21:37:08 2008 +0000 clockevents: prevent multiple init/shutdown commit 9c17bcda991000351cb2373f78be7e4b1c44caa3 upstream Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> is reported to cause a resume regression on Lenovo x60, x41 and x61 (probably other Lenovo boxes are affected as well) with 2.6.25.18. At the same time, the 2.6.27.y kernels are reported to work correctly for the affected users. Can you please try to identify the upstream commits that fix the problem on these boxes?
