Hmm, so the fixes branch by itself is fine and so is the commit before merging it. The only commit that I see that can actually imact this seems to be 1ee47b0. Can you try reverting that? The full list of changes in the fixes branch is this: $ git log --oneline --stat v3.4..74c4375 74c4375 ARM: spear6xx: remove board selection options arch/arm/mach-spear6xx/Kconfig | 18 +++--------------- 1 file changed, 3 insertions(+), 15 deletions(-) 1b6c352 Merge tag 'omap-fixes-non-critical-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux b6d3597 Merge tag 'v3.5-fixes-and-cleanups' of git://gitorious.org/linux-davinci/linux-davinci into next/fixes bdbaaf1 Merge branch 'for-3.5/fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into nex b2f44dc ARM: OMAP: igep0020: Specify the VPLL2 regulator unconditionally arch/arm/mach-omap2/board-igep0020.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) 0d09a95 ARM: OMAP2+: INTC: fix Kconfig option for TI81XX arch/arm/mach-omap2/irq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) d723c17 ARM: OMAP2+: remove incorrect irq_chip ack field arch/arm/mach-omap2/irq.c | 1 - 1 file changed, 1 deletion(-) 33ee0db ARM: OMAP4: Adding ID for OMAP4460 ES1.1 arch/arm/mach-omap2/id.c | 5 ++++- arch/arm/plat-omap/include/plat/cpu.h | 1 + 2 files changed, 5 insertions(+), 1 deletion(-) def1dbb ARM: OMAP4: panda: add statics to remove warnings arch/arm/mach-omap2/board-omap4panda.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) 256a4bd ARM: OMAP2+: Incorrect Register Offsets in OMAP Mailbox arch/arm/mach-omap2/mailbox.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) 28ee793 ARM: OMAP: fix trivial warnings for dspbridge arch/arm/mach-omap2/dsp.c | 5 +++-- arch/arm/plat-omap/devices.c | 4 ++-- 2 files changed, 5 insertions(+), 4 deletions(-) 98e3b33 arm: davinci: use for_each_set_bit_from arch/arm/mach-davinci/dma.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) 1ee47b0 ARM: OMAP4: hsmmc: check for null pointer arch/arm/mach-omap2/board-4430sdp.c | 44 -------------------------------------------- arch/arm/mach-omap2/board-omap4panda.c | 49 ------------------------------------------------- arch/arm/mach-omap2/common.h | 3 +++ arch/arm/mach-omap2/omap4-common.c | 58 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 61 insertions(+), 93 deletions(-) e54bdc1 ARM: OMAP1: fix compilation issue in board-sx1.c arch/arm/mach-omap1/Kconfig | 1 + 1 file changed, 1 insertion(+) 3d5e8af ARM: disable SUSPEND/ARCH_SUSPEND_POSSIBLE for ARCH_TEGRA arch/arm/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) 59858b7 ARM: davinci: da850-evm: fix section mismatch arch/arm/mach-davinci/board-da850-evm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) aea812e ARM: tegra: add pll_x freq table entry for 750MHz arch/arm/mach-tegra/tegra2_clocks.c | 6 ++++++ 1 file changed, 6 insertions(+) d65566e ARM: davinci: mark spi_board_info arguments as const arch/arm/mach-davinci/davinci.h | 4 ++-- arch/arm/mach-davinci/devices-da8xx.c | 2 +- arch/arm/mach-davinci/dm355.c | 2 +- arch/arm/mach-davinci/dm365.c | 2 +- arch/arm/mach-davinci/include/mach/da8xx.h | 3 ++- 5 files changed, 7 insertions(+), 6 deletions(-) 4a6e6a5 ARM: davinci: fix incorrect pdctl next bit position arch/arm/mach-davinci/include/mach/psc.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) > 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.
