[Xen-devel] 64bit Xen + iSCSI became in a dom0 crash

["Luis Vinay" <luisvinay@xxxxxxxxx>]

I'm experimenting with Xen + iSCSI on 64bit platfoms, and I founded that under heavy
stress domU's can crash entire system, I've reproduced this many many
times.

My systems are like this

Software:
- iSCSI Enterprise Target v0.4.13
- RedHat AS4 update 4 64bit + Xen 3.0.3-0 Kernel 2.6.16.29 + Open iSCSI v2.0.730 (Initiator)
- Bonnie++ v1.03a
 (stressing program)

VM:
- Debian 
3.1r3  + Open iSCSI v2.0.730 (Initiator)
- RedHat AS4 update 4 + Open iSCSI v2.0.730 (Initiator)

Perfomed tests:
Four instances of bonnie++ with root uid on the filesystem to be stressed

On all the cases the result was a crash, but when I switch to a 32bit distro everything works fine

The attached files are the captured crash errors on the cosole
