Hi.
Trying to mount a cdrom with mcdx 1.8 and 1.3.77. Sometimes the drive
seems to fail to read the disc and with previous versions, mcdx would
fail to mount the drive.
However, this just happened again and now it seems to have hung mount.
I've tried killing mount, but it won't die. The mcdx module is loaded
and rmmod won't remove it. The CD isn't mounted, however trying to mount
it again gives a resource busy message and umount says "not mounted".

The following is what shows up in kerenl logs:
12:02:34: dot kernel: VFS: Disk change detected on device 14:00
12:02:34: dot kernel: mcdx: transfer() sector 64 from nirvana requested.
12:02:34: dot kernel: mcdx: do_requst() read error

Notice the spelling error on last line. That's reporoduced form logs,
not a typo.
Like I said, I've seen the messages before and usually mount just
failes with varying degrees of grace. However, this time, it just
stopped. All other VCs are fine and I can switch back and forth with no
problem. The VC I tried mounting from however doesn't have a prompt. I
can type and characters appear, but ^C doesn't work and killing mount,
even with -9, doesn't work...
Hmm, ok. Just killed the shell on that console and that got me back to
the login prompt. However, there is still a mount process which can't be
killed.
Strange...
