Subject: 2.5.66-bk5 spinlock warnings/errors
Date: Tue, 01 Apr 2003 22:01:02 -0600 [thread overview]
Message-ID: <87el4l4kg1.fsf@mcs.anl.gov> (raw)
I am running 2.5.66-bk5 on an thinkpad t21. This model has BIOS
suspend to disk function that is independent from the OS. (I think
that this is implemented as S3BIOS in ACPI)
I am using the laptop with apm, and whenever i hibernate to disk and
resume, i get the following in dmesg:
uhci-hcd 00:07.2: suspend to state 3
include/linux/seqlock.h:52: spin_lock(kernel/timer.c:c0341894) already locked by include/linux/seqlock.h/52

Any pointers/patches would be appreciated.
