I'm not *starting* to experience them, I have been for a bit.
I infrequently get this kind of error message:
/kernel: ad0: WRITE command timeout tag=0 serv=0 - resetting
/kernel: ata0: resetting devices .. ad0: DMA limited to UDMA33, non-ATA66 cable or device
/kernel: done
This has happened on a bunch of 4.8-STABLE/4.9-PRERELEASE kernels:
FreeBSD 4.8-STABLE #0: Mon Aug 18 21:20:49 PDT 2003
FreeBSD 4.8-STABLE #1: Sat Aug 23 13:53:24 PDT 2003
FreeBSD 4.9-PRERELEASE #2: Mon Aug 25 17:34:08 PDT 2003
FreeBSD 4.9-PRERELEASE #3: Wed Aug 27 06:49:36 PDT 2003
FreeBSD 4.9-PRERELEASE #4: Sat Aug 30 09:09:03 PDT 2003
FreeBSD 4.9-PRERELEASE #6: Tue Sep 2 21:13:12 PDT 2003
Date of cvsup corresponds to date/time of compile (or pretty close).
It didn't happen under the original -RELEASE, but I may not have spent
enough time running it to trigger the problem.
FreeBSD 4.8-RELEASE #0: Thu Apr 3 10:53:38 GMT 2003
Right now I've forced myself into PIO mode by adding this into
my /boot/loader.conf
hw.ata.ata_dma="0"
Since doing that, I haven't managed to cause the problem to repeat.
