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.
