patch for omap and tegra configs to enable MMC support (built-in)

Description of problem:

The latest kernels (3.6.x) fail to boot from SDCard on Panda (OMAP) and Trim Slice (Tegra).  The F17 kernels would boot from SDCard, so this appears to be a regression.  The issue is a change in the kernel config files that made MMC support modules instead of built-in.  Since the modules are not loaded correctly, or do not function correctly as modules, the rootfs is not found, causing the boot to fail.

I suggest reverting the config changes until functional MMC module support has been completed.

Version-Release number of selected component (if applicable):

  3.6.0-0.rc3.git2.1.fc18 (and newer)

How reproducible:


Steps to Reproduce:
1.  Install latest kernel for OMAP or Tegra
2.  reboot

Actual results:

  Fails to find the rootfs on the SDCard.

Expected results:

  Systems find the rootfs and completes the boot.

Additional info:

The last known-good version from F17 was: kernel-3.5.3-1.

Using the attached config changes (based on the 3.5.3 kernel), both systems boot from SDCard as expected.

I have some issues with this patch. For OMAP at least it looks like we have a cleaner fix.

Comment 2 D. Marlin 2012-09-27 12:10:25 UTC
Specifically, what issues?

Do you have a scratch build that incorporates the 'cleaner fix' that we can test?

Comment 3 Peter Robinson 2012-10-17 12:29:11 UTC
Fixed in 3.6.1
