[OOPS] Linux 2.6.14.2 and DVB USB

[Chris Rankin]

Hi,

My Linux 2.6.14.2-SMP kernel has just exploded on me, after I detached my USB2 DVB USB adapter.
This is on a UP PIII 1GHz Coppermine machine. There was a storm of:

dvb-usb: bulk message failed: -19 (2/0)

messages between the disconnection and the eventual oops. Note also that the DVB device was
attached to a USB2 hub.

Cheers,
Chris
