Bad: scheduling while atomic!

Bad: scheduling while atomic!

[Lukas Schrangl]

Hi!

I've been trying to get S4 working for several weeks now using kernel 2.6.4  
and it still does not work.
Going to sleep with "echo -n 4 > /proc/acpi/sleep" works - but i get some APIC 
error (don't know exactly - can't read that fast).
When powering on again it first start normal, but then there is an endless 
loop displaying "Bad: Scheduling while atomic!" and a call trace again and 
again very fast. I can only hard- poweroff my computer.
Disabling local APIC does not help.

S3 does not wake up either (fan and hd spin up and then silence). Once, with 
minimal kernel configuration I managed to get a picture again on the screen, 
showing the same "Bad: Scheduling while atomic!" thing.

Maybe someone can help me getting S4 working!
Lukas

 I get the same error with suspend to disk on a Fujitsu P2120. Ali 1535
 chipset is the common bit... 

 Whats the network card you use?

Trun off APIC in kernel config and try without that broadcom network
card.

i need to unload bcm4400 before suspend (swsusp, ACPI S4) and reinsert
after resume, otherwise resume fails. Maybe the same is true for S3.

The problem was enabling both preemptible kernel and MCE. Using only one of 
them everything works, even if b44 is inserted and Local APIC enabled.
Only usb makes problems:
On wakeup I get something like
"Badness in usb/hcd/....c"
and a call trace. Will try to resolve that problem (maybe unloading usbmodules 
works, haven't had time to try yet).
After resume, I am not able to use usb anymore (even unloading/realoading 
doesn't work).
And ACPI- poweroff does not work anymore. When shutting down I can read:
"The system will be haltet immediately.
acpi_power_off called"
or something the like, but no nothing happens; i poweroff manually. On 
"normal" shutdowns (when not having resumed from S4) I don't get the msg 
"acpi_power_off called" and it powers off.
Should I write a bug report because of the preempt/MCE problem and/or the APIC 
error which seems not to have any influence?
