Kernel Bug Tracker – Bug 10131
ASUS P5LD2-VM failed to resume if smp enabled
Last modified: 2008-03-12 06:30:23 UTC
Distribution: ubuntu hardy 8.04
Hardware Environment: ASUS P5LD2-VM ( i945g + ich7 + pentium d 940 )
PC can't wakeup if smp is enabled. Workaround is to boot with nosmp.
Suspends seems have a lot of trubles on this PC. I need to use libata.noacpi=1 Bug 9804 and enabled s3_bios and s3_mode quirk for intel grafick.

Do you know if any earlier kernel versions worked OK?
No. This will be alot of work becouse i shortly upgrated my system from nonsmp with celeron d to smp with pentium d
I haw less problem with celeron d or with kernel option nosmp
kernel 2.6.23 olmost working... i mean, it can randomly wake up after short sleep ( like 1 min ) and newer after long one.
here is dmesg with 2.6.23 from Bug 9930

Please boot with nohz=off with/without highres=off and see if it can resume back.
Normally display will be disabled after resume, but with options nohz=off and/or highres=off and/orr hpet=disabled and kernel will oops alot. I can't get proper log of oops: 1. after resume ttyS0 do not send any thing ( or becouse i get on client notebook ...irq4 warning ). So i can't debug it with COM. 2. thirst opps is not on the screan, i can't get a picture.
How is about kdump, i newer did it before. Will it work with suspend/resume and should i configure kernel for it with hpet, nohz, loapic enabled like host kernel do?
I made some more tests. I have 2GB of RAM, if use only 1GB it working. There is 2 ram blocks each 1GB, they installed to use dualchannel mode but it don't make eny difference. I tested it with memtest and no errors found.
So now, known working konfigurations are: nosmp or mem=1G or unistall one memory block
I tryed agp=off but this oopsed kernel.
Latest "working" kernel is 2.6.21. This kernel can resume and go to xorg, but dmesg give:
[ 140.432000] kernel BUG at mm/mmap.c:1999!
[ 140.432000] invalid opcode: 0000 [#1]
[ 140.432000] PREEMPT SMP

Will you please set "CONFIG_PM, CONFIG_PM_TRACE, CONFIG_ACPI_DEBUG" in kernel configuration and do the following test? (Please use the latest kernel, 126.96.36.199)
a. boot the system with the option of "acpi_sleep=s3_bios libata.noacpi=1 initcall_debug"
b. echo 1 > /sys/power/pm_trace
c. echo mem > /sys/power/state to enter suspend state
d. press power button to confirm whether the system can be waked .
e. If the system can't be waked, please restart the system
After test is finished, please attach the output of dmesg.

dmesg 188.8.131.52 debug
Magic number: 0:340:984
kernel 184.108.40.206 will cleanly resume after of suspend 2-3 min. After 30 min of suspend it crash on resume.
Thanks for the test.
It seems that the system can be waked if only suspend 2-3 mins.
Will you please do the test as required in comment #15 after the system is suspended for 30 mins?
Sorry, it seems to be my mistake. I autmaticly used /etc/acpi/susped.sh instead of of echo mem > /sys/power/state. With last one it working perfektly.
some how this script /etc/acpi/susped.sh make kernel oops on SMP system. But, i think, this is other bug.
Now the laptop can be resumed from S3 state normally when "echo mem >/sys/power/state" is used.
The bug will be rejected.
