[Bug 720055] Re: Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8
A similar-looking bug has started to sting me when building with certain combinations of config options, particularly CONFIG_THUMB2_KERNEL. A good way to debug this kind of thing is to build a uniprocessor kernel with all caches (including any external L2) disabled -- this makes the memory system behave in a much less asynchronous way, so you have a chance that the abort will be received close to the code which provokes it. (For reasons to do with SMP memory sharing, an SMP kernel may not work properly with caches turned off, so it's best not to try that.) In the end, I tracked it down to the following lines in drivers/video/omap2/dss/dss.c : 117 #ifdef CONFIG_OMAP2_DSS_SDI 118 SR(SDI_CONTROL); 119 SR(PLL_CONTROL); 120 #endif After turning all the caching whizziness back on again, a kernel with those likes commented out still works, with no abort. This is unlikely to be an acceptable fix, but it could be useful clue for someone who knows about the hardware. If anyone else who can currently reproduce the bug can see whether the same fix works, that would be useful.

i had a similar oops when bringing up another on-chip core (the SGX). It turned out that the core's power and clock needed to be turned up before executing code that poked at its registers; the imprecise data abort reflected an aborted fetch from a memory location mapped to a powered-down on-chip core. Your oops may be related to the issue addressed by http://gitorious.org/linux-omap- dss2/linux/commit/096b38e85e9512b6eddd08d33f0adcb5b45573fe . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/720055 Title: Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After reading Dave's comments and takeing a look at Andy Green's config I found that if I turn off CONFIG_OMAP2_DSS_SDI the problem goes away which makes sense since Dave said commenting out 117 #ifdef CONFIG_OMAP2_DSS_SDI 118 SR(SDI_CONTROL); 119 SR(PLL_CONTROL); 120 #endif made the problem go away. So is panda init missing some clock init for DSS_SDI somewhere?

[Bug 720055] Re: Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8
Sorry, should have warned you. You are seeing the master image boot at the top before the system gets deployed. You need to look further down in the boot log to see the new image booting: Linux version 2.6.37-1003-linaro-omap (buildd@gourd) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-2ubuntu2) ) #6-Ubuntu SMP Fri Feb 11 18:49:17 UTC 2011 (Ubuntu 2.6.37-1003.6-linaro-omap 2.6.37) For reference, the previous day's image booted just fine on this same machine. This is an automated daily test of linaro images and hardware packs. ** Changed in: linux-linaro (Ubuntu) Status: Invalid = New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/720055 Title: Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
