[Xen-devel] Problem with Dell Poweredge 1850

[Rob See <rob@xxxxxxxx>]

All,

        
	I seem to be experiencing the same problem that Michal Urbanski talked 
about in an email dated March 24th with a subject of "hanging dell 
hardware". Looking through the archives I can not find any resolution to 
the problem. The specs on my machine are
Dell Poweredge 1850
Dual Xeon 2.8s
1gig ram
PERC 4e/SI raid controller in mirror configuration with 2 73 gb drives 
(uses the megaraid_mm/megaraid_mbox modules)
Any time the system is placed under high IO ( for example untar/bz2ing a 
tarball to create the fs for a xenU partiton) the machine hangs. There 
are no kernel messages. The console becomes completely unresponsive 
(pressing Caps lock does not change the status of the caps lock light) I 
can't use the magic sysreq key. I've tried adding "watchdog" to the end 
of the grub line that loads xen.gz. That didn't change anything. I've 
also tried disabling hyperthreading with no success. I'm using xen 2.0.5 
with a 2.6.10 xen0 kernel. My raid controller bios is already at version 
516a (the newest I can find on the dell site.) Does anyone have any more 
suggestions for me.
Thanks,
-Rob
