2.6.36-rc3 NULL pointer dereference crypto_destroy_tfm+0x50/0x70

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Started hitting this since rc3.

System has 6 cifs mounts from the one server, during shutdown they get
unmounted and gives this error.
If manually unmounting one at a time with a gap inbetween it doesn't
seem to happen.

config attached.
