[linux-dvb] Skystar2 causing page allocation failure

[Anssi Hannula <anssi.hannula@mbnet.fi>]

Hi!

After running fine for few days with some module reloads etc, now 
loading the skystar2 causes page allocation failure. I'm certain a 
reboot would do the trick (and I'll do it right after sending this), but 
this might still be a bug.
I'm using custom kernel 2.6.8.1-8mdk (gcc3.4) and dvb-kernel CVS.
I have two skystar2 and one dvb-ttpci card.

The module still loads and is able to FE_HAS_LOCK, but no data in dvr0.
Is this a bug in the dvb-kernel or in the kernel itself?

The following messages come to dmesg: (loading only skystar2+dependencies)
