xen discuss - Apr 2008 - panic ... recursive mutex_enter installing a snv_85 domU on Linux dom0

While attempting to install snv_85 as a domU, Debian etch as the dom0, the
kernel panics before the rest of the system starts to boot.  Currently
I''m using the sid releases of xen 3.2 found in Debian sid.  I stopped
using 3.0.3, as it appears I''m unable to use a ramdisk setting.

# dmesg | grep -i mem
...
Memory: 1903728k/1949252k available (1623k kernel code, 36208k reserved, 593k
data, 148k init, 1203788k highmem)

3.2.0-4 xenstore-utils

I was able to boot and start installing off of a 66-0624 kernel+ramdisk. 
However, when I boot the installed system I get the same results.  I can boot
with 66 manually, and I''m forced to choose between two installed
OS''s.  The suggested workaround for editing  blkif.py was already
applied.  I decided to start over and only use svn_85.  I already wiped the
first 20mb of /dev/mapper/Debian-opensolaris with 0''s.

I don''t think chgset ''unavailable'' has anything to do
with it, as I''ve seen that same message in an Oracle blog screen-shot.

Here''s what happens when I try to install...

I succeeded with SNV85 DomU install at F8,CentOS 5.1,Ubuntu 7.10 Dom0 (with
native
Xen 3.1 enabled). Xen 3.2 broke backward compatibility . It is a root cause of
the issue.
Install SNV85 DomU at Xen 3.2 CentOS 5.1 (Ubuntu 7.10) Dom0  panics immediately.

He has a workaround on the go

Using the Google source code search, I found
http://dlc.sun.com/osol/netvirt/downloads/ has net-virt_XB_BETA_snv_81_030708
and boots without issue on xen 3.2 (debian sid xen packages backported to etch)

Now I get to have a little fun and poke around.

Thanks =-)
