Including security fixes (which I had left to Bodo and Jeff at the beginnin= g)=20 required destabilizing the -bb tree, which would otherwise have been a real= ly=20 stabler version.

That is not the intention. Just unapply it for now, and help diagnosing the= =20 problem. Also, make sure *that* patch is at fault... start reverting end=20 patches away (with patch-scripts, please, don't go doing it by hand, it's a= =20 bit of a massacre) and report when it works again. I would expect the probl= em=20 to be a bit earlier (except if you also tested -bb3 or something such). > because it doesn't when i tell it to > sometimes it even segfaults, when halting or rebooting. Ok, let's say it this way: UML happens to reboot depending on how much luck= y=20 you / your box are. On my system, with *any* UML version, out of three reboots, I get on averag= e=20 two correct reboots and one segfault. I only can get it to reliably *crash*= =20 on reboot by applying an obviously correct patch (Jeff Dike is still=20 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. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
