Any -bb version you mean, I hope.

Including security fixes (which I had left to Bodo and Jeff at the beginning) 
required destabilizing the -bb tree, which would otherwise have been a really 
stabler version.

One *big* and basical problem was fixed exactly in -bb4, which explains why 
it's stabler for you.

The bug was in uml-signal-delivery.patch IIRC. It's very big, and when I was 
compelled to merge it to include further security fixes depending on it, I 
was very worried about it giving problems.

But since the first reports I got were just about trivial issues which were 
easily fixed (I got *real* bug-reports much later), I just thought it was ok 
(and I wasn't able to reproduce at all the problem).

That is not the intention. Just unapply it for now, and help diagnosing the 
problem. Also, make sure *that* patch is at fault... start reverting end 
patches away (with patch-scripts, please, don't go doing it by hand, it's a 
bit of a massacre) and report when it works again. I would expect the problem 
to be a bit earlier (except if you also tested -bb3 or something such).

Ok, let's say it this way: UML happens to reboot depending on how much lucky 
you / your box are.

On my system, with *any* UML version, out of three reboots, I get on average 
two correct reboots and one segfault. I only can get it to reliably *crash* 
on reboot by applying an obviously correct patch (Jeff Dike is still 
astonished that it can hurt anything).

For Bodo, it only works with the patches at the end, not otherwise. For me 
it's no difference without those.

Hearing that for you rebooting *worked* makes me just wonder a bit more.

The fact it halts when halting is something new, however.
