I recently upgraded one of our Consensys SVR4 systems from a 386DX/33 w/ 8 meg
to a 486DX/33 w/ 16 meg.  The system seems to run fine, with the exception of
some occasional strange hard disk activity (or non-activity).  During periods
of high disk activity, sometimes the hard disk (a 210MB IDE) light just stays
on and all disk activity just sits there.  About 20 seconds latter, the disk
starts churning again and all continues as normal.  The only clue I have is
that twice, I received "NOTICE: HD: interrupt with no request queued" on the
console. (Note that the problem described above has happened about ten times
that I am aware of, but I can force it by duing any intensive disk activity).

Any Ideas?

I have a couple of questions for any one who's got the time...

1) mach(1) and arch(1) still return 386/AT and i386 respectively.  Is this a
generic response for 486 and 386 or does my kernel need to know that I switched
processors on it?

2) Is there a real need to change the kernel or swap parameters for the added
8 meg of memory.  I know the swap area could be increased, but it's hardly
being used now???

3) Could any poorly adjusted BIOS parameters explain the above problem?

4) Anything else a must change for this upgrade?

Thanks VERY much in advance,
