Whaaaaaaa..
I was able to repeat this a few times yesterday, when I was sitting in
front of the machine. But now I cannot. I was able to get it to stop
completely thrashing by limiting the kernel call trace dump. That
allowed me to actually see what was going on. I got a single crash
dump that showed me to crash at the return call from
afs_linux_read_bytes(), which leads me to believe that there was some
sort or stack corruption happening!
However, I cannot recreate this anymore, remotely. I didn't change
anything. well, thats not true -- I rebuilt libafs.o with a printk to
try to figure out what was going on, but once I did this, it worked
fine. Then, reverting to the original libafs.o causes it to work fine
again, too...
However this is remotely, via eklogind. Perhaps it only works on the
console???
This is with linux 1.1.85 with linux-afs 1.1.85, with versioned
kernel, versioned libafs, and old insmod....
Blah. Back to the drawing board.
