[Pkg-xen-devel] how to get debugging output from dom0 kernel

[lee]

Hi,

how could I get better debugging output from the dom0 kernel?

The kernel crashes after some time and debugging output to the console
is being scrolled off by messages about NMI stuff trying to do
something.

I'm using Debian stable and would like to make a bug report, but without
any useful information there's no point.

So far, all I can say is that it seems to take over 12 and less than 24
hours before the kernel crashes, and the one time I could see the
debugging output, it seemed to be related to the xen_blkback module
which might not like the aacraid module.  It has crashed three times so
far.  This goes along with having created a second logical volume on the
raid controller (still undergoing auto-sync) which has two LVM volumes
on it in a LVM volume group.  One of the LVM volumes is made available
to a domU:


disk = ['phy:/dev/vg_guests/lv_jupiter,xvda,w', 'phy:/dev/vg_mydata/lv_DATA,xvdb,w']


It didn't crash before adding the second volume.  I can't have this
server crashing all the time --- what can I do?

Is there a more recent kernel which might work better?
