Here's output from htparm:

/dev/hda:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 2494/255/63, sectors = 40079088, start = 0

Does this provide the info you need?

I believe another chap responded to my post with a similar issue (also
SMP machine).

Uptime now 21:55 with no oops.
