I am able to reliably repeat a hard system lockup when attempting
to dump any of my filesystems that are on a DEC DSP-3105 disk to
tape (or /dev/null, for that matter). Dumping the other disk on
this system (a Toshiba) seems to work ok.
Note that this system is running -current supped as of 2/18 at
0800 GMT.
Here is the dump output of two attempts on the two filesystems on
this drive:
bob@han-p0 /home/bob> dump 0bBf 10 2000000 /dev/null /usr/obj
DUMP: Date of this level 0 dump: Mon Feb 19 10:37:34 1996
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rsd1s1e (/usr/obj) to /dev/null
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 99352 tape blocks on 0.05 tape(s).
DUMP: dumping (Pass III) [directories]
*** The system locks up at this point ***
Hmm, just tried a different filesystem and here is what I got:
bob@han-p0 /home/bob> dump 0bBf 10 2000000 /dev/null /usr/src
DUMP: Date of this level 0 dump: Mon Feb 19 10:42:06 1996
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rsd1s1f (/usr/src) to /dev/null
DUMP: mapping (Pass I) [regular files]
DUMP: mapping (Pass II) [directories]
DUMP: estimated 232413 tape blocks on 0.12 tape(s).
*** The system locks up at this point ***
The dmesg output (w/the -v boot flag) for this system looks like:
