Bug#648751: linux-image-3.0.0-1-rt-amd64: rcu_preempt_state whileshutdown
 
Hi Ben,

I've installed 3.0.0-6 and in my preliminar analysis it worked,
but after using the laptop for awhile it now said:
"irq 16: nobody cared (try booting with irqpool option)"
"Disabling irq #16"
Stopped there for about 2 minutes and said something about task halt and
sync_something


I'll try to boot with irqpool and post back.

Additionally I saw 2 call traces regarding sched.c lines 4234 and 4265 in
dmesg.


I can post if you think it's helpful

Thanks!

Dear Maintainer,

When I shutdown my laptop I get errors like "rcu_preempt_state stalled on
CPU

1" after "Will now halt." message and I can only shutdown if I hold power
button.

[...]

Please test version 3.0.0-6.

Ben.

Bug#648751: linux-image-3.0.0-1-rt-amd64: rcu_preempt_state whileshutdown
 
Hello Flávio,

you reported this bug against version 3.0.0-3 which contains 3.0.1-rt11.
Could you please retry with the most recent rt patch?

As the 3.0 kernels are not in Debian any more, you can download an image
from

http://debian.pengutronix.de/debian/pool/main/l/linux-2.6/linux-image-3.0.0-2-rt-amd64_3.0.0-6ptx1_amd64.deb

(once the public archive is completely synced). 3.0.0-6ptx1 contains
3.0.9-rt25.

Best regards
Uwe
