However, I have the same behaviour as the patched 2.6.30 (so: no BUG, 
but the mesh_abort messages).

Would it be possible for you to roughly find out at what kernel version
it stopped working ? (Some kernels may need my patch to avoid crashing)

2.6.29 works OK
2.6.30-rc1 doesn't work (BUG...)
2.6.30-rc1 with your patch ... seems to hang when it should be mounting the root directory.

Is it worthwhile doing a git bisect?
