Hi,

I recently aquired a Compaq DS10L, and I've installed a new harddrive
and put it to use as bulk builder.  However, I notice that there
appears to be problems with the interrupts from the IDE controller.
I've swapped out the old 40p cable with an 80p one, but that didn't
make any difference, so I'm now running with PIO mode I/O to the IDE
drive.

I notice that it says

  aceride0: primary channel interrupting at isa irq 14

and

  aceride0: secondary channel interrupting at isa irq 15

during probing, but on first use, it says:

  stray isa irq 15
  stray isa irq 14
  stray isa irq 14
  stray isa irq 14
  stray isa irq 14
  stray isa irq 14; stopped logging

Is this a software issue?  (I suspect it is...)

Since it's currently doing bulk builds and I'm circa 900km away from
the machine, it's a little inconvenient for me to try to debug this
further right now, but it would be nice to have some hints so that I
can try to get it into better shape sometime after I return to work
just after New Year.

Output from dmesg follows below. =


Best regards,
