There are almost impossible to debug.
Try copying vmlinux out of your guest and attach with gdb when it
hangs. Then issue the command
(gdb) thread apply all backtrace
to see what the guest is doing.

Do not meddle in the internals of kernels, for they are subtle and quick to

Hi,
I compile gentoo-sources-2.6.31-r10 and with this kernel "emerge -e world"
complete without errors!
Interesing. Can you so a git bisect to see where it stops working?
I always use the same .config
After I try gentoo-sources-2.6.34 and vanilla-sources-2.6.34 but the problem
remain, the compile freeze and I see this in ps -elf:

All in wait?
Maybe a block driver problem? Are you using virtio?
After this test I reboot in 2.6.31-r10 and I complete emerge -e world succefully.
The problem show always with all kernels>=2.6.32
I have setup something wrong in kernel? I post the .config in the previous email.
It should work for all .configs.

I have a truly marvellous patch that fixes the bug which this
