To Soren: I don't know if you mind being copied directly, my apologies if
you do; I think you handle most of the ata stuff...
Yesterday I upgraded to 4.2 from 4.1.1 via cvsup. This worked perfectly,
no errors (thank you developers). When I rebooted, however, I started
getting the "ad0: READ command timeout tag=0 serv=0 - resetting" errors.
It eventually fell back to using pio mode. I know about the sysctl work
around for this problem (for those desktops with certain (fujistu) drives
and certain chipsets, but udma33 mode worked for this notebook before the
upgrade.
The system is an Acer 343T, using the AcerLabs Aladdin ATA33 controller,
which I know from the ata man page is supported (and worked well! from
personal experience). The dmesg is at the bottom.
The kernel configuration for the ata section is simply using:
device ata
device atadisk
device atapicd
options ATA_STATIC_ID
The end of the first ad0 line now reads WDMA2, but I know it was UDMA33
before. Please tell me if there's any information I'm forgetting, or if
there's anything I can do to help track this problem. I see from the
stable list that there are a few other reports of similar problems.. I
wonder if they are related.
(If anyone wonders about the ppc0 line, that's simply because I turned off
the lpt port in the bios, and has never caused problems before.)
Anyway, thanks for your time.
