Hey guys

I have an old SGI indy R4600 and have installed debian testing with
latest linux-mips cvs kernel. I found two problems with the programs
hwclock and df. Apart from that appears to work fine. I have included
their output. I don't know if it is a kernel or package problem. I don't
know if it as something to do with preemtible kernel which I enabled in
kernel. If anyone is interested and wants to see kernel .config, fstab
or anything else I'm happy to oblidge.

P.S. feel free to ignore me. It does not really worry me that they don't
work, but I thought maybe someone would want to know.
