2.5.66-bk5 spinlock warnings/errors

[Narayan Desai]

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

Any pointers/patches would be appreciated.
