Today (5/18/1999) I experienced a crash on a 2.2.8 kernel. On the screen was the line: kmem_alloc: Bad slab magic (corrupt) (name=size-2048) several times. I was unable to telnet or ping the system, and the console was unresponsive. I was unable to change virtual terminals. Pertenint parts of /var/log/messages are attached.
Natuarally, this appears to be related to Linux's VMM. I suppose it could be a hardware problem, but I've had no difficulties until now.
here is the output from uname -a: Linux macc.ml.org 2.2.8 #11 Thu May 13 10:52:34 PDT 1999 i486 unknown
the output from the ver_linux script and /proc/cpuinfo are attached.
Let me know if there is anything else I can do to help.
