Hello,
I've just hit the following bug with 2.5.67. Since 2.5.68 is already out and I
haven't had a chance to run it on that particular machine yet, it'd be good if
someone could comment on whether this is a known issue or maybe already fixed.
The machine in question is a Pentium-166 with a 100 MB SCSI Zip drive connected
to an Adaptec 2940 Ultra SCSI adapter. The file system on the zip disk is ext3.
The bug happened when the disk was mounted.
See kernel output below. The whole dmesg output is also available in case
someone is interested.
Regards,
-Udo.
