Hi,
I hardly can't believe it. This night (after I was formatting the last one of my QIC80 backup tapes <g>), my Linux system (kernel 2.1.128) died just out of the blue.
The death resulted in a very bad filesystem corruption (superblock has gone and a few directory entries). Fortunately, I had the chance to plug in the drive into another Linux machine and was able to repair most of the filesystem and - more important - to save all my private data.
I got the following messages, when I tried to boot linux in my machine: (On sda1 is an old DOS version with loadlin, which I use to load linux)
Partition check: sda: sda1 sda2 sda3 (Here, a strange noise appeared) aha1542.c: Trying device reset for target 0 Sent BUS RESET fo scsi host 0 scsidisk I/O error: dev 08:03,sector 2 EXT2-fs: unable to read superblock scsidisk I/O error: dev 08:03, sector 0 FAT bread failed kernel panic: VFS: unable to mount root from 08:03
Well, on the other machine, I was able to run e2fsck with the superblock at pos. 8193 (how can I *boot* linux and specify, that the superblock is at 8193?). There were some twenty errors, but almost all data could be restored.
In the syslog of the other machine (who uses a AHA2940), I got a lot of entries like the following:

My question now - who (except me for missing backups :-) is to blame here?
- My aha1542 (quite unlikely. It never made *any* problems in the past) - my DCAS 43440 (it's just 10 months old...) - Kernel 2.1.128 (2.1 kernels worked absolutely fine for me since more than half a year. Never the slightest problem) - something else, not mentioned here?
