2.6.22 hangs at boot on my box. Here attached a original dmesg from 2.6.21,

dmesg because it's not logged to disk yet); it actually stops right after
'init' launches.
Ok, the guilty bit is gcc: in my box, compiling kernel with gcc 4.2.x
(which is installed on my debian/sid) turns into a hang (in init,
seemingly, maybe not even in kernel itself), while gcc-4.1 is allright.

I have the same problem, also on Debian sid on amd64. I can report that the
Debian version 4.2-20070627-1 of gcc works, 4.2-20070707-1 does not.

Also the hang occurs in udevsettle; if you wait long enough (60 seconds?)
then udevsettle times out and the boot continues (but doesn't get very far
with an almost empty /dev).

I suspected it was something about /dev populating, but I hadn't any clue on how to make it go on. To be sure, I've left it "hanging" (actually, it's not a completely unresponsive hang, SysRq works fine) for even 15 minutes, without any luck.

Could you please try to compile 2.6.22-git1 and see if you get an internal gcc error? It is in the first kernel-core related files, you should hit it too.

This evening I'll be able to be more precise about the exact file, I don't have the box here.

Bye.
