Having built the openstack from crowbar openstack111219.iso we have been building VMs and accessing them without an issue, we had the odd crash of the compute node and have been working on identifying the issue, it appears that when a user is logged into the VM and tries to download and install software on the VM it will suddenly crash the compute node, we have done this across two different nodes (same hardware M610 blades).

Nothing in dmesg but I managed to capture the crash from a console:
[ 4304.459030] BUG: scheduling while atomic: swapper/0/0x10000200
[ 4304.459109] Modules linked in: ebt_arp ebt_ip ip6table_filter ip6_tables ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_i
[ 4304.486540] [] ? dma_issue_pending_all+0x76/0xa0

Had no luck on finding these issues online.
