[Xen-devel] BLKTAP causing kernel BUG at arch/i386/mm/hypervisor.c:71
I have further blktap woes. I recompiled xen-unstable with blktap on
major number 244 (arbitrary choice) to avoid major number clash on 254.
However, subsequently:
[root@dom0-0-50-45-5d-59-aa ~]# blktapctrl
Debug output from /var/log/messages (syslog):
Sep 21 15:34:46 dom0-0-50-45-5d-59-aa BLKTAPCTRL: blktapctrl: v1.0.0

Sep 21 15:34:46 dom0-0-50-45-5d-59-aa BLKTAPCTRL: /dev/xen/blktap0
device already exists
So far so good(?). There is a running blktapctrl process, no longer
pinned at 100%. So, I try to create a tap:aio device:
[root@dom0-0-50-45-5d-59-aa ~]# xm block-attach 0
tap:aio:/tmp/sparse.img /dev/xvda1 w 0
At this stage all hell breaks loose, culminating in a hypervisor panic.
Here''s the log:
