Bug#495793: linux-image-2.6.26-1-openvz-686: kernel panic when running netstat
Package: linux-image-2.6.26-1-openvz-686
Version: 2.6.26-2~stable0
Severity: important
Hi!
I backported the linux-image-2.6.26-1-openvz-686 package using pbuilder to try openvz on my etch server. It runs ok until I run netstat like this:
alex@atlantis:~$ netstat -ltn
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

tcp 0 0 0.0.0.0:139 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN
It produces several lines and then the machine hangs.
I was able to write down only these lines:
