No, I'm afraid not. It's still the same effect:
root@5va2:~# dmesg -c >/dev/null
root@5va2:~# strace -o dd.strace dd if=/dev/mcdx0 of=/dev/null
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00438956 seconds, 0.0 kB/s
root@5va2:~# dmesg >dd.xtrace
dd.strace again attached. I've dropped the mutex patch for now and now
the xtrace is littered with waitqueue debugging. I'll see if I can
disable that particular debugging trace I guess. dd.xtrace sent privately...
"readcd dev=/dev/mcdx0 f=foo.img" is still an immediate hard lockup also
without the mutex. I believe the "tar" runs has produced something
useful now though:
root@5va2:~# dmesg -c >/dev/null
root@5va2:~# strace -o tar.strace tar cvf foo.tar /mnt/cdrom
tar: Removing leading `/' from member names

When I now switch the monitor to 5va2 directly, there is an oops on the
screen, with a backtrace saying (manual transcription):

Couple of functions mentioned twice in that backtrace. That looks a
little off no?
"tar.strace" made it to disk, so it's attached as well.
