As written in the subject, it just hard hangs before writing anything on

I'll try and bisect this, but it takes some time (since the bios and
post process takes forever). I just updated the firmware on the box as
well, but it did boot 2.6.32 (and RHEL5 boots fine too). Of course that
doesn't rule out a BIOS bug.
Results are persistent, git bisect points to:

x86: Move find_smp_config() earlier and avoid bootmem usage
which appears consistent with the panic(). Reverting that does indeed
make current -git boot properly.
Thanks. Yinghai, do you have any ideas, or should we revert it?
