Re: Bug#699470: crystalhd-dkms: Kernel null pointer BUG in crystalhd_dioq_fetch_wait()
It looks like the crystalhd drivers are buggy with newer kernel releases. I opt for removing the dkms package. I will do this over the weekend.

Until and unless the driver is in mainline, there's every reason to drop it. Cheers, Julien I just checked the crystalhd driver in the mainline kernel. The driver seems to be much better maintained over there than at linuxtv.org. See [1]. I'm going to drop the driver from linuxtv.org. If after I drop the package someone has some compelling reason to use the driver from linuxtv.org, they can submit another bug to the crystalhd package and explain why the linuxtv.org driver should be used. 1. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/staging/crystalhd -- ~ Andres ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-multimedia-maintainers
