Hide Forgot
Description of problem: I've installed FC7T3 and it tries to boot but when it tries loading udev it locks up with the message: "the code is fine but needs lockdep annotation. > [13440.772455] turning off the locking correctness validator." and some debug printout. If I blacklist the b2c2-flexcop-pci module than FC7 boots right. Version-Release number of selected component (if applicable): Fedora 7 Rawhide How reproducible: 100% every reboot Steps to Reproduce: 1.modprobe b2c2-flexcop-pci 2.see the lock 3. Actual results: System freeze Expected results: working dvb :-) Additional info: I've an Technisat Airstar 2 DVB-T Card.
Created attachment 151655 [details] Patch to fix the problem In the flexcop-pci.c spin_lock is used before it was initialized by spin_lock_init. Hope to include this.
Has this been sent upstream at all yet? I don't see it in the main v4l-dvb tree, but that doesn't mean someone already knows about it... If not, Michael, can I talk you into taking a look at it? :) I've got a box with a b2c2-flexcop-pci card I can throw a rawhide kernel at pretty easily to see if I can reproduce and validate the fix, if it helps.
Patrick maintains this driver... There is discussion in the following thread: http://linuxtv.org/pipermail/linux-dvb/2007-April/016985.html
Mauro pushed the patch into v4l-dvb.hg master repository today: http://linuxtv.org/hg/v4l-dvb?cmd=changeset;node=a80058519add
Works fine with the latest kernels in my own b2c2-flexcop-pci box.
