I keep getting ResierFS oopses on my test box here. It's a Cobalt Raq4i
running the 2.4.17 kernel (with some of my own experimental code in the
kernel but I don'tthink this is the cause of the problem). The box has
been powercycled and paniced more times than I've had hot dinners so I
suspect that these oopses are being caused by hard drive corruption. The
ksymoops output is below:

One of the buffer_head addresses (which should have been either a
valid address or zero) in fact had a value of 0x00000002. Single
bit error; probably bad memory/CPU/etc.
