SubjectRe: OOPS in 2.3.99pre3-8: cat /proc/ide/sis
Well, I tried, in 2.3.99pre3. And it still gives the attached OOPS...

I don't know if there's any more help that I can provide? I've seen it
working about 1 or 2 weeks ago, and noticed a typo somewhere even, but I
really can't remember which kernel version that then was! I'm pretty
sure it was after the SHM changes though.
