This caused system hangs after resume from S3 when HPET was used in one-shot mode on such systems because a timer interrupt was missed (HPET signal is high active). For more details see: http://marc.info/?l=linux-kernel&m=129623757413868 Tested-by: Manoj Iyer <[email protected]> Tested-by: Andre Przywara <[email protected]> Signed-off-by: Andreas Herrmann <[email protected]> Cc: Borislav Petkov <[email protected]> Cc: [email protected] # 37.x, 32.x LKML-Reference: <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> ------------------------------------------------------------------------ My pc has SB600, which has its own early-quirk.c entry. I noticed one more thing. When you try to reboot the bad kernel,the screen turns black and the optical drive makes noise "Bz-zz" as usual, but it doesn't proceed any more. (At least 20 secs.) Correct reboot would show the HP logo at the next step. I reverted this patch on top of 2.6.38, it seems to run like 2.6.36, i.e. almost ok, for hours. Let me ask: there's another acpi bug between 2.6.34 and 36 for my PC. I understand that acpi drivers underwent serious rewritement after 2.6.36. Will a bisect reveal the problem? (See the next message for the bug detail.) My impression is "no". I suspect that there's a persisten bug in my hardware or in the kernel, and it interplays with the kernel acpi code changes. Thanks a lot for taking care of this issue. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
