From irc conversation with sakoman CONFIG_OMAP2_DSS_SDI should not be turned on for a board without an sdi display. Here is the very informative discussion: sakoman__ jcrigby: the proper fix for the vdds_sdi regulator issue is to unset CONFIG_OMAP2_DSS_SDI in your defconfig sakoman__ none of the indicated boards use an sdi display, so it makes no sense to set that! sakoman__ so I won't be submitting a vdds_sdi regulator patch for Overo (it wouldn't be accepted anyway due to the above!) lool sakoman__: What happens if you turn on CONFIG_OMAP2_DSS_SDI for another board in the same kernel? sakoman__ you will likely get a regulator error when compiling boards that don't have sdi displays sakoman__ lool: I would be surprised if you have a board with an sdi display sakoman__ lool: N900 is the only board that I know of which uses sdi sakoman__ tomba has already stated that he will not accept patches adding sdi regulators for boards without sdi displays sakoman__ it is just the wrong way to fix the issue lool sakoman__: Turns out that some people are enabling N900 in Ubuntu, and I was wondering whether we should enable it in our kernels! lool sakoman__: Can we make the effect of CONFIG_OMAP2_DSS_SDI more runtime than it is right now? sakoman__ well, if you do, then the proper fix would be in sdi.c, not in board files lool sakoman__: I believe you :-) lool Or rather, I'll take your word for it sakoman__ that is where the real issue is in that it requests the regulator always, not just when an sdi display is used so the proper fix is what I thought was just a workaround. Turn off CONFIG_OMAP2_DSS_SDI. -- 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: CONFIG_OMAP2_DSS_SDI on OMAP4 causes: 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

Changing the bug description to reflect the current status. Next verson of package will have CONFIG_OMAP2_DSS_SDI turned off so we now have graphics on omap4/panda. ** Summary changed: - Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8 + CONFIG_OMAP2_DSS_SDI on OMAP4 causes: Unhandled fault: imprecise external abort (0x1406) at 0x2ada61a8 -- 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: CONFIG_OMAP2_DSS_SDI on OMAP4 causes: 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
