Re: [Xen-devel] credit2 BUG_ON triggered

I'll try 4.1-testing again with the patch reversion.
4.1-testing is now doing the same thing as unstable for me -- the domU
freezes after "(XEN) HVM5: Writing SMBIOS tables ..." -- and only when
credit2 is being used.
I did get it to "work" (panic) once, but then saw that it said debug=n.
After that, I rebooted, did a "make clean" + recompile, and repeated my
test, and it still said debug=n (this must be a separate build issue),
so I completely wiped, checked out, reverted, recompile,d and tried
again, leading to the current situation.
Here's what it said when it *did* crash. This is partial output because
the later reboot overwrote part of the screen in ipmitool:
(XEN) irq.c:324: Dom3 callback via changed to Direct Vector 0xe9
(XEN) Xen BUG at sched_credit2.c:811
(XEN) ----[ Xen-4.1.1-rc1-pre x86_64 debug=n Not tainted ]----
(XEN) CPU: 12
That means that it died at one of your special debug lines:
BUG_ON(test_bit(__CSFLAG_scheduled, &svc->flags));
I'm trying to find a way to reproduce that output.
