Hello. Please excuse my misusing the 'questions' mail box for a bug
report. I am new with FreeBSD
and have not yet configured it for sending e-mail. This is what happened
to me a few minutes ago when
I was playing with FreeBSD:
I put a RW CD of unknown contents into the drive and tried
mount -t cd9660 /dev/acd0c /cdrom
This had the dramatic effect of a fatal system crash (with a kernel
message starting with a 'trap 12 ...'
story), followed by an automatic reboot. Apparently, in the course of
rebooting the root partition was somehow repaired (at least I hope so).
As I had previously verified that mounting a CD with an iso9660 file
system worked well, the conclusion
was obvious that the effect depended on the contents of the particular
CD. Indeed it turned out that
it had been burnt as an audio CD. So it appears that the OS does not
tolerate what I did, i.e.,
confusing audio and iso9660 CDs. The next thing to do would have been
trying the same with a
commercial audio CD. However, I refrained from that to avoid another
crash possibly resulting in
permanent damage of the file systems.
Here comes a little information on my system:
Computer: PC , 400 MHz Pentium II, SE440BX motherboard, 128 MB RAM,
2 Western Digital harddisks, 1 CDRW drive Traxdata 8432. No SCSI.
The harddisks are
master and slave on IDE 1, the CDRW drive is master on IDE 2.
OS: FreeBSD 4.3-RELEASE, downloaded from the net.
Sincerely,
Ernst Terhardt
