Well, as Matt has said, I reported a crash that he's trying to debug. Since
I have the 686b in my machine, I applied the patch. Ever since then I was
not able to reproduce the crash again, although yesterday it was so easy
that I could do it twice an hour ;-)
Anyway, you (Soren) said that the right way to fix this is a BIOS update.
Now, could it be that some mainboard manufacturers are incapabel of
handling this? I'm using the latest BIOS for my board, and according to
http://www.chaintech.com.tw/DL/7xMB/7AJA0.HTM, this should already have
been fixed in their BIOS release from 2001-04-23...
Second interesting thing: I was using a UDMA66 drive on my 686b until a few
weeks ago and never had any problems - the stuff Matt is looking at only
started two appear a short while after I exchanged that drive for a UDMA100
one. So, it seems as if probably the slower drive didn't produce a high
enough PCI workload for anything to actually happen.
This fix will probably also have some influence on a few other similar
problems (I read Matt was working on many of them). In the end I hope that
this fix - or a variation thereof - will actually go into 4.5.
