Sorry guys, I did the email by memory (bad idea). Actually, what I did: 849 qemu-nbd -p 2000 /root/qemu/q1.img & 850 nbd-client -persist localhost 2000 /dev/nbd0 851 ps aux | grep nbd 852 echo reboot >/sys/power/disk 853 echo disk >/sys/power/state At the prompt after the hibernate (test mode: 'reboot') I see the following: /build/buildd-qemu_0.12.5+dfsg-3squeeze3-amd64-9wXBnc/qemu-0.12.5+dfsg/nbd.c:nbd_receive_request():L465: read failed [1]+ Done qemu-nbd -p 2000 /root/qemu/q1.img ================ Looks like 'qemu-nbd' exited on some signal. No other indicators. I see no other relevant messages in syslog. In dmesg I see the message (as expected): Sep 26 13:27:13 debian-test kernel: [606754.367766] Freezing user space processes ... Sep 26 13:27:13 debian-test kernel: [606754.367840] nbd (pid 8432: nbd-client) got signal 0 Sep 26 13:27:13 debian-test kernel: [606754.367844] block nbd0: shutting down socket Sep 26 13:27:13 debian-test kernel: [606754.367872] block nbd0: Receive control failed (result -4) Sep 26 13:27:13 debian-test kernel: [606754.367890] block nbd0: queue cleared ================ Thank you, Mark T.
