[2.6.2-rc1] Oops while rmmod'ing parport_pc (PnP related?)

[Rui Saraiva]

	Hello,

	I got this Oops while rmmod'ing parport_pc. Acording to
/sys/bus/pnp/devices/00:01/resources, PnP device 00:01 is my parallel port.
I'm using "options parport_pc dma=3 io=0x378 irq=7" in /etc/modprobe.conf.
After this I was unable do read /proc/modules or run any process that uses
it, as it has stale in D state... I could only reboot with SysRq+B.
	If you need more info, just ask.

	Regards,
		Rui Saraiva
