[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] kernel BUG at block/bio.c:1786 -- (xen_blkif_schedule on the stack)
I get the BUG below in dom0 when trying to start a windows 10 domu (hvm,
with some pv-drivers installed ) . Below is "xl info", then comes dmesg
output, and finally domu config attached at end.
This domain is started very rarely, so may have been broken for some
time. All my other domains ar linux. This message is just a data-point
for whoever is interested, with possibly more data if anybody wants to
ask me anything. NOT expecting quick resolution of this :-/ .
The domain boots part of the way, screen resolution gets changed and
then it keeps spinning for ~ 5 seconds before stopping.
