Red Hat Bugzilla – Bug 1836
Use of the Token Ring Module hangs Redhat with error

Actually, it's 5.9.0, since I can't get to 5.9.1 - yet.
After loading the ibmtr.o module, the user gets to watch the
screen fill up with the following alternating messages :
tr0: out of memory. frame dropped.
kmem_alloc: bad slab magic (corrupt) (name=size-128)
At this point, the system is unusable. You cannot access the
console, and you cannot three-finger-salute the system.
This didn't happen under 5.2 with the 2.0.x kernel series on
the same system. Since I never put 2.2.x on 5.2, I don't
know if it'll happen in that case. I do know that this will
be a problem.
We believe this was a kernel bug, please test with a 2.2.4 or higher
kernel and report back whether or not this fixes your problem.
OK, I've upgraded to a 2.2.5, and I'm seeing the same thing. Although
I'm not sure if the 2.2.5 modules are being used. I'll reinstall and
CC Alan so that he can follow the bug

Is the kernel update for RH 6.0 (2.2.5-22) fixing the problem?
reopen if not.
Haven't heard any complaints from my IBM people, so I'm closing the bug.
