Consistent kernel panic on volume mount


I've run into quite a scary issue. Some defect RAM has managed to mess up my internal SATA drive - and yes I know this happens all the time and nothing special about that!  Well the thing is that not only does this lead to a kernel panic when booting on the drive - it seems that whenever this drive is mounted on any Mac running 10.3.x it leads to an instant kernel panic similar to this one:


panic(cpu 0): jnl: do_overlap: overlap of 0 is not multiple of 24

Latest stack backtrace for cpu 0:
       Backtrace:
          0x000833B8 0x0008389C 0x0001ED8C 0x000CF86C 0x000CFAEC 0x000CFE80 0x000D0B08 0x001E476C

I'm guessing that journaling is involved here and I'll have to disagree with the statement that 0 is not a multiple of 24 :) Booting in single user mode on the drive leads to a similar message. I've also tried booting in single user on another drive and mounting it with mount_hfs -j which supposedly turns of journaling but the result is exactly the same.

It seems to me that this is a pretty serious problem since not only does it prevent the usage of standard disk recovery tools - it even prevents the normal user from reformatting such a drive. So apart from the fact that I'd love to be able to recover some data from this drive I also think it would be great if someone knew how to fix the code - seems kind of ironic if it is in fact journaling that prevents disk recovery!

Oh and if someone  could tell me whether it would be appropiate to file a bug on an issue like this please let me know.
