The following reply was made to PR kern/24401; it has been noted by GNATS. From: "Ronald F. Guilmette" <rfg@monkeys.com> To: "Justin T. Gibbs" <gibbs@scsiguy.com> Cc: FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: kern/24401: Advansys SCSI driver crashes random userland progs w/SIGPROF Date: Fri, 19 Jan 2001 10:59:21 -0800 Just one further follow-up on this problem... After having replaced ALL the memory on the system, I coutinued to see the X server die at seemlingly random times. In short, it was clear that I still had a problem. Now however I had some reason to suspect that my video card might be playing a role in this. Then I remembered what I had in there... It was a relatively ancient PCI video card... an S3-based Number Nine Motion 771, circa 1995. I swapped that out and dropped in a low-end ATI AGP card that I had on another system *and* I put back all of the original SDRAM DIMMS and then I re-ran my test that was consistantly failing before (i.e. the small pro- gram that just zwrite a big stream of zeros to a second SCSI disk). That worked flawlessly now. I ran two full tests, writing all the way to the end of the disk (4GB) with no problems. That's enough to convince me that the original problem I reported must have been due to some bad interaction between the Advansys PCI SCSI controller and this particular old PCI video card. It seems that these two just don't play well together. Serves me right for trying to use antiquated components. Humph.
