It's a different issue. This will solve it -- http://git.linaro.org/gitweb?p=people/andygreen/kernel- tilt.git;a=patch;h=1b0d6d49516d29bf2d723e2789e6f0fcd483f7b7 On OMAP, if you try to touch any peripheral unit that is not clocked, it'll blow a bus abort which shows up as one of these imprecise external aborts. MUSB has recently taken on runtime_pm which means units are unclocked more often when out of use, and evidently it's not 100% yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745737 Title: Kernel panic when rebooting panda board -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 745737] Re: Kernel panic when rebooting panda board
Before the attached patch I got the error 9 of 54 resets. After the patch I reset 50 times with no occurance of the bug. I will apply the patch to the packaged kernel as a SAUCE patch. The patch is an updated version of one Anand posted as a possible fix for the other panda display crash bug. ** Changed in: linux-linaro Status: Incomplete = Confirmed ** Also affects: linux-linaro-omap (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-linaro-omap (Ubuntu) Status: New = In Progress ** Changed in: linux-linaro-omap (Ubuntu) Assignee: (unassigned) = John Rigby (jcrigby) ** Patch added: This is a workaround not appropriate for upstream https://bugs.launchpad.net/ubuntu/+source/linux-linaro-omap/+bug/745737/+attachment/1958379/+files/0001-SAUCE-OMAP4-clock-wait-for-module-to-become-accessib.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745737 Title: Kernel panic when rebooting panda board -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
