Hello! I have a strange error with a CMD Technology/Silicon Image 680
Raid/IDE controller card. I used debian with a 2.4.21 kernel.
I have a IDE hard disc (WD 9.5 GB, old disc) that I have tested on the
controller on the motherboard, I can create an ext2 filesystem on it, and
read/write. No problems (after 5 minutes of testing)
When I put the harddisc on the controller card, I get bad results.
Directly after boot:
dmesg |grep hde
ide2: MMIO-DMA , BIOS settings: hde:pio, hdf:pio
hde: WDC AC310000R, ATA DISK drive
hde: attached ide-disk driver.
hde: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hde: task_no_data_intr: error=0x04 { DriveStatusError }
hde: host protected area => 1
hde: 19541088 sectors (10005 MB) w/512KiB Cache, CHS=19386/16/63, UDMA(33)
hde: [PTBL] [1216/255/63] hde1
hde: DMA disabled
That doesn't look good :-(
cat /proc/interrupts |grep ide gives
10: 2416 XT-PIC ide2, usb-uhci, usb-uhci, eth0
14: 8641 XT-PIC ide0
15: 25 XT-PIC ide1
so the controller shares the irq (if that now is of any matter, I don't
know)
Now, hdparm /dev/hde is set to
/dev/hde:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 1216/255/63, sectors = 19541088, start = 0
busstate = 1 (on)
I read a few hundred files, mounts and unmounts 20 times quickly. I first
get the errors (in syslog):
(8 times)
kernel: hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
kernel: hde: dma_intr: error=0x84 { DriveStatusError BadCRC }
kernel: ide2: reset timed-out, status=0xd0
hde: status timeout: status=0xd0 { Busy }
kernel: hde: DMA disabled
Then the munting starts: here is a summary of the errors:
kernel: ide2: reset timed-out, status=0xd0
kernel: end_request: I/O error, dev 21:01 (hde), sector 88 (same error for
a lot of sectors between 0 and 104)
kernel: FAT:unable to read boot sector
kernel: end_request: I/O error, dev 21:01 (hde), sector 0
and so on...
It finaly stops.
Now I can't mount the filesystem.
A while after the first errors, the disc appears not to be there... fdisk
-l /dev/hde shows noting.
But hdparm -i /dev/hde shows the same thing as before:
/dev/hde:
Model=WDC AC310000R, FwRev=15.01J15, SerialNo=WD-WM6510174466

AdvancedPM=no WriteCache=enabled
Drive Supports : Reserved : ATA-1 ATA-2 ATA-3 ATA-4
I have moved around the cables in the box to reduce electro magnetic
interference (i.e.) I have placed the 80pin cables as far away from each
other as possible (I have the internel controller's cable, and the card's
cable).
Please, can someone helt me with this? Feel free to ask me for more
information.
