I've got a machine currently running RELENG_6 solidly, but trying to
put -CURRENT on it causes the ata subsystem to go out to lunch. This
also happened on this machine with an early-March -CURRENT.
The system has a Promise TX2200 SATA controller. dmesg from RELENG_6
(slightly rewrapped):
atapci0: <Promise PDC20571 SATA150 controller> port
0xc000-0xc07f,0xc400-0xc4ff
mem 0xeb420000-0xeb420fff,0xeb400000-0xeb41ffff irq 15
at device 13.0 on pci0
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0
ata4: <ATA channel 2> on atapci0
[...]
ad4: 238475MB <HDT722525DLA380 V44OA80A> at ata2-master SATA150
ad6: 238475MB <HDT722525DLA380 V44OA80A> at ata3-master SATA150
ar0: 238475MB <Promise Fasttrak RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad6 at ata3-master
There is another ATA controller onboard running the DVD drive:
atapci1: <VIA 8235 UDMA133 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,
0xd400-0xd40f at device 17.1 on pci0
ata0: <ATA channel 0> on atapci1
ata1: <ATA channel 1> on atapci1
acd0: DVDR <PIONEER DVD-RW DVR-110D/1.11> at ata0-master UDMA66
but I don't know if that matters.
Any significant drive access will cause the drives on the Promise
controller to wander off into la-la land. They'll end up getting a
bunch of (hand-transcribed):
ad4: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA: <various>
It may happen on ad4, or on ad6. Once it held off long enough for me
to almost complete an installworld of the -CURRENT world (which
_royally_ screwed me, since I couldn't boot the old kernel then).
Sometimes even if I leave it very quiet, it'll eventually fall over
with very little drive activity. I can provoke it pretty quickly with
a `find / | xargs cat >> /dev/null`.
Running RELENG_6, it's solid as a rock, running months at a time. I
can nail the disk to the wall at will, and it won't even blink. But
let -CURRENT at it, and it'll blow beets if you look at it hard.
Unfortunately, as it runs my mail (where I'm typing at the moment), I
can't really take it down to experiment much with.
