Hmm. Well, that last conversation seemed to come to a concensus that a known thermal problem with a chip on my DELL motherboard related to heavy use of the on-board adaptec and on-board ethernet might have been the cause. I replaced the motherboard and moved away from the on-board ethernet (threw in another PCI card), and the problem went away.
I don't know if your problem below is the same problem or a different problem. It sounds like it may be a different problem.
IMO it is quite different, as I changed the following parameters:
* opened the PC to allow free air circulation (*iff* that does anything)
* replaced the on-board 7880UW controller by a PCI AHA-2940UW card. While both offer the same functionality, and are made by the same manufacturer, they also share the same timeout problems.
In my first mail I said I had seen 4.2-STABLE work and 4.3-STABLE fail, but that was not true: the old system was 4.2-RELEASE, and I noticed the error for the first time with 4.3-RELEASE).
So I upgraded to 4.3-STABLE afterwards, no change. So I got the cvs source tree of dev/aic7xxx/ to see the differences between 4.2-RELEASE and 4.3-RELEASE. But the gratest change seems to be in the sequencer code, about which I don't understand very much... In the source file aic7xxx_freebsd.c (that's where the ahc_timeout() prints the messages) I see that only little changed since 4.2-RELEASE: a detach routine was added, but IMO it is only invoked then the device is released completely. In aic7xxx.c, a LOT has changed.
Can the changes in the sequencer code be the reason for the still re-occurring "lost interrupts" on higher load -- or what else can be causing the timeout?
Or can the presence of a second (non-wide) 2940 which is used for my DAT cause any problems of this kind?
Puzzled,
Martin
