Hello
(please CC me when replying)
I gott this drive connected to the sata controler (it's the only
drive, the other two ata buses are pata):
Model=Maxtor 6L200M0 , FwRev=BANC1E00
Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=?16?
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5
AdvancedPM=yes: disabled (255) WriteCache=enabled
Drive conforms to: ATA/ATAPI-7 T13 1532D revision 0: ATA/ATAPI-1,2,3,4,5,6,7
ata3.00: ATA-7: Maxtor 6L200M0, BANC1E00, max UDMA/133
ata3.00: 398297088 sectors, multi 16: LBA48 NCQ (depth 0/32)
ata3.00: configured for UDMA/133
Note: I beleive here the reports of dmesg and hdparm diverge. iirc
udma/133 is udma6.
FIrst I got a board with via chipset, and when it died I replaced it
with one with intel chipset.
The problem was there probably for a long time and went unnoticed
until the via board started dying and I looked into the logs. It
usually manifested while playing video that required something between
95% and 115% of the available cpu power to decode properly so I
assumed it is just mplayer catching up with realtime.
I get resets like this from time to time:
Sep 8 16:44:08 heretic ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0
action 0x2 frozen
Sep 8 16:44:08 heretic ata3.00: cmd
b0/d8:00:00:4f:c2/00:00:00:00:00/00 tag 0 cdb 0x0 data 0
Sep 8 16:44:08 heretic res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask
0x4 (timeout)
Sep 8 16:44:08 heretic ata3: soft resetting port
Sep 8 16:44:08 heretic ata3.00: configured for UDMA/133
Sep 8 16:44:08 heretic ata3: EH complete
Sep 8 16:44:08 heretic sd 2:0:0:0: [sda] 398297088 512-byte hardware
sectors (203928 MB)
Sep 8 16:44:08 heretic sd 2:0:0:0: [sda] Write Protect is off
Sep 8 16:44:08 heretic sd 2:0:0:0: [sda] Mode Sense: 00 3a 00 00
Sep 8 16:44:08 heretic sd 2:0:0:0: [sda] Write cache: enabled, read
cache: enabled, doesn't support DPO or FUA
These are only noticable vhen doing realtime stuff like video playback.
When playing with stuff like noapic or pci=routeirq earlier I got
crashes instead of ata resets (there is not much you can do with a
system where the only drive gets disconnected, even if it does not
panic right away). With some combination of these I got a spurious
interrupt instead of timeout.
Thanks
