FreeBSD 3.2-19990522-STABLE: when dd'ing /kernel to write protected
floppy, it doesn't panic, but I can't kill this process in any way and
this process doesn't finish in reasonable time. I waited about 10
minutes and then rebooted computer - it couldn't correctly shutdown, said
"Syncing disks" and rebooted. After restart it said that / wasn't
properly dismounted. Almost panic, without panic message...
While dd'ing it logs lots of information about this process, something
similar to:
cdrw /kernel: fd0c: hard error writing fsbn 0 of 0-3 (No status)
^^^^^^^^
and this for all source's size space
and then, without pause:
cdrw /kernel: fd0c: hard error writing fsbn 0 of 0-3 (ST0 40<abnrml> ST1 2<write_protect> ST2 0 cyl 0 hd 0 sec 1)
And again and again and again... Infinite loop. Not good, as for me.
Ok. dd'ing boot.flp (2949120 bytes) to write protected 1.44 fd gives such
result:
dd if=boot.flp of=/dev/fd0
dd: /dev/fd0: end of device
358+0 records in
358+0 records out
182784 bytes transferred in 49.324598 secs (3706 bytes/sec)
^^^^^^
Note transferred size. Even not 1.44Mb...
and then panic with message:
panic: vinvalbuf: dirty bufs
Third test: dd'ing boot.flp to write enabled 1.44Mb floppy is correct
- 2881+0 records in, 2880+0 records out. BUT! When used bs=8192, FreeBSD
hanged immediately.
And last: quite unexpected behaviour when eject diskette from drive while
dd'ing to it something. In my case it was panic with message:
fd0c: hard error writing fsbn 81 of 80-83 (No status)
fd0c: hard error writing fsbn 84 of 84-87 (No status)
fd0c: hard error writing fsbn 81 of 80-83 (No status)
fd0c: hard error writing fsbn 81 of 80-83 (No status)
fd0c: hard error writing fsbn 81 of 80-83 (No status)
fd0c: hard error writing fsbn 81 of 80-83 (No status)
panic: vinvalbuf: dirty bufs
syncing disk... 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 giving up
Automatic reboot in 15 seconds ...
...
So, work with FDD still unstable in FreeBSD 3.x
