[Fwd: [openib-general] ib_mthca can't be removed in some error case]

[Hal Rosenstock]

A few more messages came out and then the module removal ultimately
timed out and completed. Not sure I trust the state of things after this
though...

Hi,

When I /sbin/modprobe -r ib_mthca (after having umad and IPoIB up and
then removed and a switch and SM come and go), the removal hangs up as
follows:

29836 pts/5    D      0:00 /sbin/modprobe -r ib_mthca
uninterruptible sleep 

I get the following error in the system logs:
Dec  1 09:31:17 localhost kernel: ib_mthca 0000:02:00.0: HW2SW_MPT
failed (-16)
Dec  1 09:32:17 localhost kernel: ib_mthca 0000:02:00.0: HW2SW_MPT
failed (-16)
