[Xen-devel] Assertion '__task_on_runqueue(prev)' failed, line 458, file schedule.c

[Kip Macy <kmacy@xxxxxxxxxxxxxxx>]

I'm using stock gcc3.3.2 as included with the Fedora Core 2 pre-release.
Everything works fine for me with a build from May 15th.  I'm compiling
with nodev and debug enabled.

This corresponds to
ret_from_hypervisor_call
do_sched_op
__enter_scheduler

Any suggestions as to what I'm doing wrong? I'm using the exact same

Thanks.
