I've spent the past few days trying to get my new OnStream DI-30 IDE
tape drive working, with little success. I thought I might have a
hardware problem, but the drive works fine under windows (backup and
compare of a 2G partition works correctly consistently). For good
measure, I even replaced the IDE cable with the one supplied with the
drive - that made no difference.
Although I've seen other problems, the most consistent one seems to be
a problem with verifying a tape. I can do a tar of a 1.2G partition,
and that will work fine. However, a compare of that same partition
aborts relatively quickly, with messages like this:
May 22 00:09:20 lydia kernel: ide-tape: ht0: skipping frame,
logical_blk_num 3015 (expected 8)
May 22 00:09:20 lydia kernel: ide-tape: ht0: couldn't find logical
block 8, aborting (block 3015 found)
May 22 00:09:20 lydia kernel: ide-tape: ht0: skipping frame,
logical_blk_num 3015 (expected 9)
May 22 00:09:20 lydia kernel: ide-tape: ht0: couldn't find logical
block 9, aborting (block 3015 found)
The weird part is the references to block 3015 are very, very common -
even with different tapes. I've gotten this error with 2, possibly 3
tapes, with different kernels, over 3 days of testing.
I'm using the patches from the OnStream web site:
ide.2.2.14.20000124.patch.gz
ide_2_2_15_20000504_patch.gz
I've played with patched versions of both 2.2.14 and 2.2.15 (both of
which are stable for me otherwise). I've tried building the kernel
using gcc 2.95.2 and 2.7.2.3. I've built it both with and without
chipset-specific support.
One other big glitch - my X server (Mach64 3.3.6) has a tendency to
lock up completely when the tape is being accessed, if you do things
like switch virtual screens around. The lock is total - keyboard and
mouse death, uninterruptible sleep. Remote logins still work, though,
and the machine can be rebooted that way. Even under heavy load, my X
server has never acted this badly.
I've also seen messages about lost interrupts on hdd (the drive is set
up as my IDE secondary slave), and DMA problems; however, my hard
drive has worked consistently with Ultra DMA access (it is a Maxtor
91020D6 10G). Also, disabling DMA on hdd using hdparm doesn't fix
things.
My system is an HP Pavilion 8260, which has an Intel 440LX chipset.
The DI-30 firmware is reported as version 1.06. My system is running
Debian 2.2 (potato). My current kernel (patched 2.2.14) uses the
following options in the block section:
CONFIG_BLK_DEV_FD=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDETAPE=m
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
IDEDMA_PCI_EXPERIMENTAL=y
CONFIG_BLK_DEV_PIIX=y
CONFIG_BLK_DEV_PIIX_TUNING=y
CONFIG_BLK_DEV_LOOP=m
CONFIG_BLK_DEV_RAM=m
CONFIG_PARIDE_PARPORT=m
CONFIG_BLK_DEV_IDE_MODES=y
I can think of more tests to try, but right now I'd just be shooting
in the dark. Anyone have a clue about what's going on?
Thanks!
