Ok, I dropped back to the 0.90 tulip driver that comes with the kernel
rather than upgrading to the 0.91. After a day's grace, the kernel is
continuing to kernel crash with the following errors:

Any more ideas? I've noticed it's only generally happened on the process
swapper, nacctd, and squid. Any help would be appricated, I'm lost to the
cause and the solution.

Thanks for any help,

Colin.
