With a SLICE kernel, any attempt at doing anything with an audio CD results in a deadlock (e.g. 'tosha -i' hanging in vn_lock state). The drive bay is locked solid, cdcontrol can't unlock it (and hangs in vn_lock). If I try to reboot, the system may or may not succeed in syncing the disks, but does not set the clean flag on the root filesystem, and either hangs after the sync or complains about a deadlock and panics (no dump available, despite running with the fixed kern_shutdown.c and autoconf.c). One other thing is that the device nodes for the CD aren't present (except for /dev/cd0) - I have to try to mount the CD first (which won't work since it's an audio CD, but will make the device nodes appear). Mounting cd9660 CDs seems to work fine. If someone wants a dump, I could try forcing a panic with the kernel debugger and see if it dumps.
