After the upgrade to Linux kernel 2.6.38, the boot process for my machine hang quite long while Populating /dev with existing devices through uevents. After investigations it turns out that the cx88 driver used for my Hauppauge WinTV HVR-1300 tv card was not correctly converted to the new mutex system while removing the BKL. This is being tracked in the kernel bugzilla as bug #31962.
Fortunately, there is a patch attached to the mentioned bug report which resolves the problem:
cd /usr/src/linux wget -O cx88-2.6.38-fix-driver-deadlocks.patch 'https://bugzilla.kernel.org/attachment.cgi?id=53722' patch -p1 < cx88-2.6.38-fix-driver-deadlocks.patch
[Edited on 2011-04-23: replaced patch 52902 with 53722]
After applying the patch, build and install your kernel as usual. But there are still some more problems with 2.6.38 related to tvtime. See also my next post.
I do not follow kernel development close enough to know in which git tree this has to show up to confirm if it has been merged yet. Hopefully this patch will make it into the next kernel release.
Glad to have found this post! My hvr1300 hasn’t been working either. It did on older kernels, but not since 2.6.37. Unfortunetaly I can’t compile my own so I hope it’ll be uncluded soon.
Still not included in vanilla kernel. 🙁 Thx for your post. Patching 2.6.38 with 53722 works for me.
