2.2.18 dies on my 486..

2.2.18 dies on my 486..

[Mike A. Harris]

I just upgraded my 486 firewall's kernel to pure 2.2.18 from
2.2.17, with no other changes, and now it dies with all sorts
of hard disk failures.

I get:

hdb: lost interrupt

And stuff about DRQ lost...

Totally frozen box after that.

Is it possible you compiled the kernel with gcc 2.95.2?  I've been having
a similar problem, but I'm having trouble tracking it down.  Because I
normally use a very heavily modified 2.2.18 kernel, I'm trying to isolate
just where the problem is - I have no problems with a stock 2.2.18 kernel.
If I compile with gcc 2.7.2.3 it works fine.

Cheers, Andreas

Absolutely not possible.  ;o)  Compiled with kgcc on Red Hat 7
(egcs 2.91.66).  I've been building kernels with egcs since Red
Hat 5.0 was released, no problems.

I've never used gcc 2.95.x at all, so I can't comment on it at
all..

It seems my hard disk may be failing...

Hmm.. must be a different problem than I'm having.  I've tracked
my problem down to disk accesses to hdb.  hda/hdc work fine, as
does the machine sitting idling doing its job.  If I do a copy
from hdb to hdc it explodes.  Very odd..  ;o(

What hardware config, what hdparm tuning options ?

No messages in syslog, but it died numerous times with "hdb
interrupt lost" and DRQ failed or something like that.  It seems
to work fine if I access any one drive, but if I copy from hdb ->
hdc the machine dies within seconds.

.config attached

I am thinking possible hardware failure, but I havent spent time
yet trying to narrow it down.

No special lilo options or any tweaking going on on this machine
other than hdparm..

I think it's probably a hardware issue, yes.  I've seen several Maxtors
doing just this kind of stuff before ... I have one @ork which gives
this kind of errors if I put the box sideways - if it stays upright, no
problems :)

Well, have you tried setting 32-bit support to '0'?  Just for hdb,
