Subject: BUG: sleeping function called from invalid context at mm/mempool.c:210

Hi,

2.6.20-1.2962.fc6 #1 SMP

When capturing video, and doing a recompile of a sofware application
(heavy disk load) things go pear shaped:

...
Jun 28 13:17:16 emachine kernel: ivtv0: Cause: the application is not
reading fast enough.
Jun 28 13:17:39 emachine kernel: ivtv0: All encoder MPEG stream
buffers are full. Dropping data.
Jun 28 13:17:39 emachine kernel: ivtv0: Cause: the application is not
reading fast enough
