Hello...
I recently got a decommisioned lab machine (Tyan Titan Pro (S1668) Board, only
one Pentium Pro 200 CPU (of two) installed) and wanted to repurpose the
machine as my internal router/web server.
As the machine was running kernel 2.4.18 (Debian Woody) I wanted to upgrade
the kernel to 2.4.26 to make sure I have all security fixes. I did some
simple hardware tests before setting the machine up and everything was fine.
After upgrading to Kernel 2.4.26 I suddenly got the following errors (usually
in identical groups of 3), and the harddisk became extremely slow:
- -----------------------
hda: drive not ready for command
hda: dma_timer_expiry: dma status == 0x20
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
- -----------------------
At first I thought the disk had gone bad and replaced it with a known good
drive (which ran without problems before and runs without problems now in
another machine), but this drive generated the same errors. Putting another
known good drive on the other controller port also yielded the same errors
(now with hda *and* hdc instead of only hda). I have also checked all cables
and tried an UP kernel without any changes. 12 hours of memtest86 also
detected no errors.
After finding that the old 2.4.18 kernel prduced no errors at all no matter
what drives were connected, I did a quick bisection search across several
kernel versions and found that all kernels upto (and including) 2.4.20 work
without problems with all drives. Any later kernel (>= 2.4.21 including
2.6.7) exposes the errors no matter what drives are connected. A little
digging around shows that kernel 2.4.21 merged the 7.00beta IDE drivers,
while the working kernels have ide.c version 6.31. So I would point my finger
in that direction...
I am currently stuck with kernel 2.4.20, so what can I do? I am willing to try
patches or help debugging, but my kernel hacking experience is limited and my
IDE expertise is non-existent, so any help is appreciated. If you need any
further information, please ask.
Thanks,
Patrick
