The ATA (definitely not SATA) controller on my Dell Latitude
C840 laptop has READ_DMA, WRITE_DMA problems, maybe 2-3 times
a day unless I turn off DMA. It hangs for 3-4 seconds, logs
errors, then proceeds. It isn't heavily loaded. I tried using
Soren's ATA mkIII patches, and now it likes to panic about that
same frequency instead of hanging, so I'm going back to the
stock RELENG_5 config next chance I get.
It's one of these:
atapci0: <Intel ICH3 UDMA100 controller> port
0xbfa0-0xbfaf,0x376,0x170-0x177,0x 3f6,0x1f0-0x1f7 at device 31.1 on pci0
I have the same problem, only worse :^< I could not get through the install
without booting in same mode. WRITE_DMA errors all over the place when
writing out the superblocks. I haven't tried the ATA mkIII patches yet, RL
has been very busy & I've not gotten back to this workstation.
It happens all the time for disk activity. There appears to be no relation
to load or activity.
It's a plain vanilla KT266A system with an 80G WDC PATA drive....
