Hi, I get this error afrer few time of working always
during this the listening of the music contained in my
EXT3 partition here the operation that I do:

>> Starting Xserver
>> Kldloading snd_cmi
>> mounting my EXT3 partition in read-only mode
>> starting listening music with XMMS

I don't have the dump, because the DEBUGGING options
are disabled, it happened to me 3 time , with
5.0-RELEASE and -CURRENT kernel , now I've turned on
the debug in the kernel , and I'll wait that the
system freeze up again in order to give some more
infos. 

What happen is this: The system freeze up, then after
few sec the system reboots.

Here the messages that appears in console:

syslogd: kernel boot file is /boot/kernel/kernel
kernel: TPTE at 0xbfc21bb0  IS ZERO @VA 086ec000
kernel: panic: bad pte
kernel:
kernel: syncing disks, buffers remaining... panic:
bwrite: buffer is not busy???
kernel: Uptime: 1h26m42s
kernel: Terminate ACPI
kernel: Automatic reboot in 15 seconds - press a key
on the console to abort
kernel: --> Press a key on the console to reboot,
kernel: --> or switch off the system now.
kernel: Rebooting...

The panic appears randomly after the boot  , it can be
an hour as can be 3 or more hours . 

Thank you very much for your time


Marcello
