Also do you use an > Adapter SCSI controller in the same time? just a quick 'state-of-the-art' : 1) I replaced TX4 (Promise PDC40718 SATA300) with some cheap Sil3114 (SATA 150) based 4-ports cards : -stable-amd64 (including last sys/vm MFC but rev. 1.268.2.4 for vm_pageout.c) is rock-solid while doing moderate heavy geom_raid5 testing of a 6-disk system including hot-swapping disk, continuous swap on an Adaptec 2940 (320 disk connected by 50->68 convertor) and continuous NFS. About 4000 irq/seconds and not the slightest problem for three days (including a lot of more or less brutal reboots) 2) same hardware with TX4 cards (-stable of a couple of days ago) crashes when only lookin at it. I switched SATA-cables, SCSI-cards, no difference 3) I just realised our main server has a TX2 (Promise PDC20378 SATA150) which is rock-stable bur running -stable-i386 of Aug 12th (and booting from IDE, no SCSI involved) voili-voila, not a clear picture, but amd64 versus i386, ATA-only versus SCSI+ATA, and/or SATA150 versus SATA300 seem credible suspects. Arno NB, /me votes in favour of including geom_raid5 in -current when code-freeze is over. IMHO this piece of code deserves wider audience and testing.
