Subject: [Qemu-devel] [Bug 1423528] [NEW] setting unsupported timeout for i6300esb watchdog causes hw reset
Date: Thu, 19 Feb 2015 12:26:12 -0000 [thread overview]
Message-ID: <20150219122612.20987.32403.malonedeb@gac.canonical.com> (raw)
In-Reply-To: 20150219122612.20987.32403.malonedeb@gac.canonical.com
Public bug reported:
Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=778291
Version: 2.1
systemd utilizes existing watchdog hardware and set's a 10min timer on reboot.
The i6300esb under qemu doesn't like such a timeout, and immediately resets the hardware:
The last message one gets is
[ 9.402243] i6300esb: Unexpected close, not stopping watchdog!
The linked bug report contains information how this bug can easily be reproduced.
With any image using a recent enough systemd as PID 1 you should be able to reproduce it by running
qemu-system-x86_64 -curses -enable-kvm -device i6300esb -watchdog-action
reset -hda <image with systemd>
I'm uncertain if this is a qemu or kernel/driver bug. If the latter, please re-assign the bug as necessary.
** Affects: qemu
