Hi, This is a real oldie, but better late than never.
A while back, I discovered that this patch would help against a kernel panic when "cat /proc/asound/card0/codec0" was executed on this machine, which was running an fglrx driver. I asked for a stable backport, but Takashi wanted testing to make sure this was actually fixed by the patch [1]. And now, several months later, I have this confirmation [2]. The test was conducted on an 3.5 Ubuntu kernel, based on the 3.5 extended stable tree, but would apply equally well to 3.4. I'm attaching the backported patch - it applied cleanly, I've just added an extra section with an explanation. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2013-March/060132.html [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1212160/comments/4 ** Patch added: "0001-ALSA-hda-Move-one-time-init-codes-from-generic_hdmi_.patch" https://bugs.launchpad.net/bugs/1212160/+attachment/3906367/+files/0001-ALSA-hda-Move-one-time-init-codes-from-generic_hdmi_.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1212160 Title: 'cat /proc/asound/card0/codec0' cause kernel panic (battery mode) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1212160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
