2.6.24 Kernel Soft Lock Up with heavy I/O in dm-crypt

[Ritesh Raj Sarraf]

Hi Christophe,

I noted kernel soft lockup messages on my laptop when doing a lot of I/O 
(200GB) to a dm-crypt device. It was setup using LUKS.
The I/O never got disrupted nor anything failed. Just the messages.

Kernel: 2.6.24
Distribution: Debian Testing/Unstable
Tainted: Yes (nvidia proprietary drivers)

I've not filed a bugzilla because my kernel is a tainted kernel because of 
nvidia drivers.

I'm attaching the messages. Please let me know if it stands as a candidate for 
a bug report.
