Hey Arnd,
So it looks like something has gone awry in the 3.5 pull with
Panda's mmc functionality. Trying to boot the current 3.5-rc tree,
the boot fails after not finding the root device. Looking at the boot
log I'm seeing:
omap_hsmmc: probe of omap_hsmmc.0 failed with error -22
With the same config on 3.4 it boots up fine. I also tried w/ the
omap2plus_defconfig and see the same behavior.
Before I start bisecting down, I just wanted to raise the issue here
in case there's a known fix.
I went ahead and tried to bisect this down, and it was pretty painful as
there's a omap-usb-host build bug somewhere near the issue that keeps me
from being able to totally isolate it.
Anyway, the bisection finally pointed to this merge:
commit 8dca6010d44cc722a94dc6da96560f9083dac782
Merge: 9bc747b 74c4375
Author: Linus Torvalds <torva...@linux-foundation.org>

Merge tag 'fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-s
Pull non-critical arm-soc bug fixes from Olof Johansson:
"These bug fixes were not important enough to have them included
in the
v3.4 release, mostly because they cover harmless warnings or
unrealistic configurations. Instead we queue them up to be picked up
in the next merge window."
Fixed up trivial conflict in arch/arm/mach-omap2/board-omap4panda.c
* tag 'fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM: spear6xx: remove board selection options
ARM: OMAP: igep0020: Specify the VPLL2 regulator unconditionally
ARM: OMAP2+: INTC: fix Kconfig option for TI81XX
ARM: OMAP2+: remove incorrect irq_chip ack field
ARM: OMAP4: Adding ID for OMAP4460 ES1.1
ARM: OMAP4: panda: add statics to remove warnings

ARM: OMAP: fix trivial warnings for dspbridge
arm: davinci: use for_each_set_bit_from

ARM: OMAP1: fix compilation issue in board-sx1.c
ARM: disable SUSPEND/ARCH_SUSPEND_POSSIBLE for ARCH_TEGRA
ARM: davinci: da850-evm: fix section mismatch
ARM: tegra: add pll_x freq table entry for 750MHz
ARM: davinci: mark spi_board_info arguments as const
ARM: davinci: fix incorrect pdctl next bit position
But I'm a little skeptical due to the huge number of "git bisect skip"s
required.
Full bisect log below, in case it helps
thanks
