Hi,

if i try this patch series the boot stops after (seeing via serial
console):

      Starting kernel ...

      Uncompressing Linux... done, booting the kernel.

without this patch series i can see the boot to th OS. I am using
this
patches on top of

      http://gitorious.org/linux-omap-dss2/linux/commits/master

Do i anything wrong or do i use a wrong git repo (the patches apply
cleanly)? Her my kernel config: http://fpaste.org/9Esw/
Hmm, I cannot even compile the kernel with that config:

please enable swap support or try:

http://ftp.arm.linux.org.uk/git/?p=linux-2.6-arm.git;a=commit;h=97594b0f35c0708cb9551c070b9693a52ec24ebf
which is fixed in 2.6.38-rc8
Ok. So you didn't have just my master branch and the HDMI patch set? I see that the config you gave is for rc8, and mine is rc7, so I guess you
also merged rc8 into your tree?

   Tomi

yes, you are right, i have tested this with different kernel configs and
both rc7 and rc8 with the same results.
Ok. I need to dig out my panda and try to get it running. Blaze board
seems to work fine, at least for me.

Does the crash happen every time?

  Tomi

omap2plus_defconfig
yes, with all configs i tried. will try a "make omap2plus_defconfig" too and
let you know.

I have tried booting on Panda board and it works fine , I am using
OMAP2PLUS defconfig.
I have disabled VENC though( without that i see that kernel hangs , ie
because reading VENC register in hwmod probe is resulting in a crash.

i have tried this omap2plus defconfig now too, with some little changes needed to boot my system (config: http://paste.pocoo.org/show/352917/). Now i get this error (see also: http://paste.pocoo.org/show/352915/)

[    3.255065] omapdss HDMI: fallback to VGA
[    3.271636] omapdss HDMI error: Failed to set PHY_PWR_STATUS

[    3.309539] omapfb: probe of omapfb failed with error -5

using omap2plus defconfig with my little changes i need to boot my system i get the error above, also if i remove CONFIG_ARCH_OMAP2. but if i remove CONFIG_ARCH_OMAP3 too i get the error i reported originally (the kernel begins to boot, but crashes) (diff between omap2plus defconfig without CONFIG_ARCH_OMAP2 and omap2plus defconfig without CONFIG_ARCH_OMAP2, CONFIG_ARCH_OMAP3: http://paste.pocoo.org/show/352960/)

thanks

Stephan
