firmware.agent Opps

firmware.agent Opps

[Jean Tourrilhes]

	Hi,

	Using 2.6.3 (SMP), prism54 driver and firmware.agent from
Debian unstable. I got the following nice Ooops :

	If you think the driver is at fault, please tell me and I'll
forward that to the prism54 guys. If you need more info, just yell at
me.

	Thanks...

 No, the driver is not at fault.

 It is a known problem, I have some pending patches which fix some races
 and should fix that. I´ll update them and send them to Andrew for
 inclusion (Simon Kelley promised to bug me until I do so :-)). I´ll cc
 lkml like usual.

 Thanks for the report,
 Have a nice day

 	Manuel
