Bug#410807: linux-image-2.6.18-4-xen-686, 2.6.18.dfsg.1-10~bpo.1: kernel BUG at drivers/xen/core/evtchn.c:481
Hi,
I run Debian 3.1 Sarge with kernel from backports.org on Dom0
Package: linux-image-2.6.18-4-xen-686
Version: 2.6.18.dfsg.1-10~bpo.1
I catch the bug $subj when starting machine Dell Latitude D820 notebook
with CoreDuo CPU (T2400). There were two DomUs to restore during boot
(/etc/init.d/xendomains). I saw this bug for the first time.
System was frozed. I used sequence Alt-Sysrq-E, Alt-Sysrq-S and
Alt-Sysrq-B to reboot. Next boot was successful and both domus was
restored normaly.
A bit from my syslog:
