Hello BSD users,

  I think the following things are pretty clear and they don't
need a loooong explanation that anyone will be able to read:
# cd /mnt
# ls -al
ls: dvdrw0: Input/output error
total 24
drwxr-xr-x   7 root  wheel  512 Feb  8 15:27 .

Yes, the CD I inserted is good. No, a dmesg for you won't be useful. And, yes, I know you would ask, here is my fstab:
/dev/wd0a / ffs rw 1 1
/dev/wd0d /home ffs rw,nodev,nosuid 1 2
/dev/wd0f /tmp ffs rw,nodev,nosuid 1 2
/dev/wd0e /usr ffs rw,nodev 1 2
/dev/wd0g /var ffs rw,nodev,nosuid 1 2
/dev/fd0a /mnt/floppy0 msdos rw,nodev,nosuid,noauto,noexec 0 0
/dev/cd0a /mnt/dvdrw0 cd9660 ro,nodev,nosuid,noauto,noexec 0 0
/dev/cd1a /mnt/cdrw1 cd9660 ro,nodev,nosuid,noauto,noexec 0 0

The optical unit is a DVD+/-RW DL, ASUS (DRW-1608P2, Rev 1.17). Processor Intel P4, 3GHz etc. You can imagine the rest... I run the standard OpenBSD 3.8 system. I don't think you would ask, but if I restart the system it's all OK. It happened to me several times; I'm not stupid, I can assure you, but every time I was tired and I cannot reproduce the situation;
My question is: what's going on here?
All commands were of course executed from the root account.


Thanks in advance


Yours in BSDness, Gabriel George POPA
