Description J. Kolehmainen 2000-04-14 15:15:48 EDT
My machine locks up after 10-15 minutes of high disk I/O either when
running backups (dump w/ Amanda) or by just gzipping very large files.  I
don't suspect HW issues because the machine worked wonderfully (1 1/2
years) foing nightly dumps running RH6.0.  The day after I upgraded these
problems cropped up.

The hardware in question is:
-Single proc AMD K6-2 450Mhz w/128M RAM and 1M cache on a Soyo motherboard
-Boot device is a WD 13G DMA/66 IDE drive.
-Problems occur across both my IDE drives one on each IDE bus, both
masters.
-Problems also occur on both my Seagate 4.5G Cheetahs (UW) on an Adaptec
2940UW.
- I have 512M of swap configured on all 4 drives (128M) each.

I have swapped out DIMMS with another machine with exact same results.  I
can do the gzip of a 700M file on any partiton on any disk and I get the
same results.  I do not get ANY messages, no Kernel panic, not even and
OOPS.  The box locks up hard and cannot even be given the Windows salute
(Cntrl-alt-deleted).  Machine must be either HW reset or powercycled.
The machines seems to come up relatively fine (a couple disks generally
need fsck'ing) and very little looks like a problem.

This is a kernel (or hardware) problem ...

Does 6.2 show this. If so what IDE controller ?
