The running kernel /proc/version
Linux version 2.2.0-pre7-ac6 (root@washu.corp.sgi.com) (gcc version 2.7.2.3) #2 Sun Jan 17 15:33:20 PST 1999
I was running netscape (v4.0?) while compiling pre7-ac6 with
arca-VM-23 patches (I'm not sure whether they are intended to be
together, there was only one problem, in the file
include/linux/sched.h '#define INIT_MM' section).
Netscape died (and now dies on startup), and make also dies trying
to compile the kernel. The oopses (quite repeatable) are as follows:

The make generates the OOPS when compiling
make[1]: Entering directory `/usr/src/linux-2.2.0-pre7-ac6/fs'
make -C lockd modules

make[1]: Leaving directory `/usr/src/linux-2.2.0-pre7-ac6/fs'
make: *** [_mod_fs] Error 2
Also, my NFS (via autofs) seems to be hung, too... (a client
mounting a disk on an SGI Indy running IRIX 6.5.2). This has
happened before, and in previous times (and previous kernels) it
froze-out my PCMCIA ethernet card... The symptoms in messages are
(there's more, this is just a part of the message log):

Plus, a HUGE amount of the physical memory seems to be locked in
cache, and it only seems to increase. from /proc/meminfo:
total: used: free: shared: buffers: cached:
Mem: 64962560 52199424 12763136 17354752 3727360 31481856

MemShared: 16948 kB

Most of my shells are hung on something. Only my remote stuff (and
local emacs) is currently working. I could open more shells... New
processes are able to start.
I'm going to reboot to this kernel again, to see how reproducible it is...
