the exact error returned by the kernel is ENXIO "Device not configured"
I tried to "ls /cdrom" after a successful re-mount (cacheing?), and then I
received:
...
ac0: WARNING - removed from configuration
acd0: WARNING - removed from configuration
ls: /cdrom: Device not configured
$
after this message the kernel panics inside g_event:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc04cd919
stack pointer = 0x10:0xcbd3cb7c
frame pointer = 0x10:0xcbd3cb94
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 2 (g_event)
trap number = 12
(sorry for the mess about info)
