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.
