Subject: es1968 locks up on rmmod
Date: Mon, 26 Jan 2004 18:12:02 +0100	[thread overview]
Message-ID: <40154A62.7080403@gmx.net> (raw)

Hi,

I have a Toshiba 4100XCDT laptop with an ES1968 chip. lspci follows:

00:0c.0 Multimedia audio controller: ESS Technology ES1978 Maestro 2E (rev 10)
    Subsystem: Toshiba America Info Systems ES1978 Maestro-2E Audiodrive
    Flags: bus master, medium devsel, latency 64, IRQ 11
    I/O ports at fc00 [size=256]
    Capabilities: <available only to root>

When the init scripts try to unload snd_es1968 on shutdown, my machine
freezes instantly.

Distribution is SUSE 9.0 Professional. Kernel is kernel-default-26-2.6.1-4
from ftp.suse.com/pub/people/kraxel which is basically 2.6.2-rc1.

I assume the lockup happens because interrupts are not disabled for the
device.

Debug traces are not available since SysRq-T and SysRq-P do not work. The
nmi watchdog does not work on my hardware. The only SysRq keys that work
are "O" and "B" to switch the machine off/reboot it.

Right now, I can disable the rmmod, but that's not a solution for long.

Please take a look at the module unloading function and fix it if possible.


Regards,
Carl-Daniel
