Apr 2 17:40:47 darkfire kernel: idle task may not sleep
the EIP value corresponds to : c0147038 T ip_queue_xmit
This could have been caused by DIP which was running at the time and
secconds before I had gotten:
Apr 2 17:37:55 darkfire kernel: TCPv4 bad checksum from 040519c8:d6bc to
180519c8:177
0, len=84/84/104
I was running X along with 2 Xterm sessions and the usual stuff. I do not
thing this could have caused the fault because the system has run so for
some days and it had not happend before. The computer is a Pentium 133 with
24 MB RAM, one 1.6GB Maxtor and one 1.2GB Conner Disks and a Trident 9440
video card. It is running kernel version 2.1.30.
