Some files of size up to 2-3GB each.

Would you send me a patch so that afsd would printk some debug text on it's startup?
Few times I was playing with the afsd process, I managed to get afs started and mounted,
but any command, like /bin/ls did not return back to the parent commandline shell.
Basically, the machine had to be reset. Yes, I could login through ssh many times,
bout could not efectively execute any single command. This is probably a different
problem compared to the startup/mount problem, but just wanted to mention this too.

I think I need printk patches if this problem should be traced.
