System: NetBSD emmas.up-vision.de 1.5_ALPHA NetBSD 1.5_ALPHA (EMMAS) #1: Tue Jul  4 10:40:00 MEST 2000 martin@wilhelminas:/usr/src/sys-i4b/arch/i386/compile/EMMAS i386


>Description:

We had serious trouble with various pieces of this machine, so we've been
replacing everything step by step. This includes power supply, processor,
memory, harddisks, IDE cables (now 80 wire ones) and mainboard. So I'm quite
sure this is not related to further hardware problems, since it survived
all those replacements:

From time to time the pciide driver goes berserk and seems to loose interrupts.
This happens both when reading and when writing. It doesn't seem to happen
on the secondary IDE channel.

Until now it was harmless (besides some connection timeouts while the
error recovery was in progress).

Dmesg output, including some of the errors, follows:
