I guess my problem is different as there wasn't this LBUG on my
client.
Are you sure? The LBUG message probably just didn't make it to the syslog server.
Do you have a serial or fake-vga console? -> any messages there?
How are you logging to the syslog server?
Kernel panics won't make it to the logserver with an userspace syslog daemon.
You'll have *much* better chances capturing a kernel panic by using netconsole.ko
