I'm seeing some resets on my ad0 drive. I tend to cvsup my kernel, recompile and reboot so the only clue I have to the version I'm running is the date that the kernel was compiled as it shows up when I rebooted. I stripped out a few reboots if there was no change in kernel rev or errors. It isn't necessarily a heavy-use CPU all the time, but I've obviously done some full compiles (make buildworld, plus the kernels). Initially I was thinking that this must have crept in around 8/23, but looking back through my logs I see another write timeout on 8/19. All the hits today took place during lots of I/O (mostly buildworld with some of the larger ports like X). I'll do some more I/O and see if I can find anything that triggers it reliably. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= [grep -e 'ad0:' -e 'done$' -e 'kernel: FreeBSD'] Jul 22 21:24:28 pandora /kernel: FreeBSD 4.8-RELEASE #0: Thu Apr 3 10:53:38 GMT 2003 Jul 22 21:24:28 pandora /kernel: ad0: DMA limited to UDMA33, non-ATA66 cable or device Jul 22 21:24:28 pandora /kernel: ad0: 9736MB <Maxtor 91020U3> [19783/16/63] at ata0-master UDMA33 ...
