Description of problem:
Kernel splurges error messages (looks like issue with aha1542)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot the machine, loading aha1542
Debug: sleeping function called from invalid context at mm/slab.c:2000
See attached log extracts

syslog including stack trace
On the machine in question the cdrom is scsi, and there's a hard disc
that is configured as swap; swapping to it causes *lots* of activity
to syslog. Slows things down!
So far I haven't detected any real errors associated with these
messages from 2.6.8 (as downloaded from fc2 updates), though I did get
a kernel panic with 2.6.5. Nevertheless it is a real nuisance, soaking
up disc bandwith logging it all.
Note that the "Debug: " line is logged at kernel.err and the stack
traces are at kernel.warning, so it would lose too much from the logs
to configure syslogd not to report them.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
