[linux-dvb] Re: What's wrong with 2.6 kernel and dvb-modules?

[Gregoire Favre <Gregoire.Favre@freesurf.ch>]

Hello,

I try to understand the problem with rmmod dvb_ttpci...

strace -o/tmp/rmmod-dvb_ttpci.strace rmmod dvb_ttpci
umovestr: Input/output error

And this stay so, then I run in another term:
strace -o/tmp/rmmod2-dvb_ttpci.strace rmmod dvb_ttpci
umovestr: Input/output error

And it also sty in that "position" without giving me the hand back...

I CTRL-C the first one, which release the hand, and the second one now
also get further:
strace -o/tmp/rmmod2-dvb_ttpci.strace rmmod dvb_ttpci
umovestr: Input/output error
ERROR: Module dvb_ttpci does not exist in /proc/modules

I attach here the two strace, maybe they could help...

Could I provide some more info to help debug this?

Thank you very much,

	Grégoire
