Ubuntu Kernel boot problems

I built a new 2.6.38-rc1-git3 Ubuntu kernel with DEBUG_LL on Kubuntu 11.04 x86_64, but it doesn't boot and I get no debug messages.

Used the following steps:-

Booted the Beagleboard C3, installed kernel-headers and linux-image.
Copied initrd.img-2.6.38-rc1-git3-custom and vmlinuz-2.6.38-rc1-git3-custom back to the x86_64 box.
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./vmlinuz-* ./uImage

mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs -d ./initrd.img-* ./uInitrd
# Copy "uInitrd" to the Boot Partition
Booted the beagleboard, but it stops as shown above.

I can supply my .config if requested.
Same problem trying to boot the Ubuntu ppa kernel 2.6.38-rc1-d0.
I copied back the original 2.6.35.6-l5 uImage and uInitrd on the SDHC and it boots.
I think I should have everything in place for a successful boot, I am out of clues.

Make sure your console is using "ttyO2" vs "ttyS2"

^yeap^ that was broken:

It was posted to the list, linux-omap list but here's the patch for reference..

https://github.com/RobertCNelson/2.6.38-devel/blob/master/patches/trivial/0001-arm-fix-oops-in-sched_clock_poll.patch

v2.6.38-rc2-d1 from rcn-ee.net should work..

I copied back the original 2.6.35.6-l5 uImage and uInitrd on the SDHC and it
boots.
I think I should have everything in place for a successful boot, I am out of
clues.

Sid.

If you are using the official TI Ubuntu Maverick from at the bottom of the page it says they turned of the console

I have tried the default tty02, but changed it to ttyS02 in the .config and rebuilt the kernel when it failed to boot.

Hi Sid,

Then i'm pretty sure your running into the same issue i saw over the weekend..

this fixed it for me, you can double check by adding teh earlyprintk
to your boot args, it should opps at sched_clock_poll..

https://github.com/RobertCNelson/2.6.38-devel/blob/master/patches/trivial/0001-arm-fix-oops-in-sched_clock_poll.patch

I think Tony pushed another fix to tovalds, i''ll give that a build tomorrow..

Regards,

Thanks, I shall check 2.6.38-rc2-git2 later.
Regards
Sid.

The patch was needed for 2.6.38-rc2-git2 so I applied it and started the build.
Regards
Sid.

I tried the patch with 2.6.38-rc2-git3, same problem. I shall add the earlyprintk and boot again later.

Sid.
