combining debug checks like this is generally a bad idea imho, since you
don't know which of them triggered...

doh.  I don't even know who to lart for that one!

Could you please boot with "initcall_debug" and then resolve the final
couple of addresses in System.map?  That'll narrow it down.

Heck it works with initcall_debug:

Red Hat Linux release 7.3 (Valhalla)
Kernel 2.6.0-test2-mm5 on an i686

I tried again without initcall_debug and it doesnt: 

Starting migration thread for cpu 7
CPUS done 16

....

What additional info you guys want? 

Full output of both with/without initcall_debug boot messages or?

Odd, odd.

Mmmm. 4/4 split now boots again, but behaves rather oddly. This is with
Nick's AS fix, plus the 4/4 fix Andrew sent me last night, which I presume
is the same as what Bill sent out.

Difficult to tell what's going on exactly. For one, the machine has lost 
it's hostname, for another, it seems to have mounted the root fs readonly. 
End of the bootlog looks like this:

----------------------

EXT2-fs warning (device sda2): ext2_fill_super: mounting ext3 filesystem as ext2

VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 288k freed
INIT: version 2.84 booting
INIT: Entering runlevel: 2
Starting system log daemon: syslogdchmod: changing permissions of `/dev/xconsole': Read-only file system
/etc/init.d/rc: line 101:   118 Trace/breakpoint trap   $debug "$@"
Starting kernel log daemon: klogdstart-stop-daemon: nothing in /proc - not mounted?
/etc/init.d/rc: line 101:   120 Trace/breakpoint trap   $debug "$@"

Debian GNU/Linux testing/unstable (none) ttyS0

(none) login: 

------------------------

Mounting the ext3 root as ext2 is normal (it's hard to un-ext3 it
whilst standing on it). The debug stuff & loss of hostname is not.
Won't accept incoming ssh connections. I can sorta start to log in
on the serial console, but readonly-ness screws it:


(none) login: root
Password: 
login(pam_unix)[129]: session opened for user root by (uid=0)

----------------------------

If I can grab any more useful info, let me know ...

It comes up normally here; not sure what's going on.
