Lost Interrupt

[SoloCDM]

The present system has operated without any changes to the hardware
with Win9.x, RH5.2, and LM7.0.  This problem only started when I
upgraded to LM8.0 and still no hardware changes have been made.

I use the 420Mb drive as a swap disk, connected along with the
CD-ROM to the secondary port.  I can't bring myself to throw the
420Mb drive out.

The following errors occur during boot-up:

Why does this happen and how can it be resolved?
