Hi Stefan,
Following are:
1) test scenario commands
2) strace from nbd-client
3) strace from qemu-nbd (quite lengthy - 598 lines)
4) kernel oops output when I 'halt' after the test scenario.
Thank you,
Mark T.
1) ==========
162 qemu-nbd --persistent -p 2000 /root/qemu/q1.img &
163 nbd-client -persist localhost 2000 /dev/nbd0
165 strace -p 2488 -o /var/tmp/qemu.nbd.strace.v2 &
166 strace -p 2492 -o /var/tmp/nbd-client.strace.v2 &
168 mount /dev/nbd0 /mnt
169 ls /mnt
172 echo reboot >/sys/power/disk
173 echo disk >/sys/power/state
180 ls /mnt <-- hangs
