Hi,
on the same platform I reported problems installing s9 in hvm mode yesterday, I 
am now also having trouble running s10.
For the second time now, patching the system has hung, the last time when patch 
119091-33 tried to execute add_adr:
s10u7-base:/# ps -ef | grep 7033
     root  7033  6105   0 10:27:43 console     0:00 /bin/sh 
/d0/tmp/10/10_x86_Recommended/119091-33/postpatch
     root  7084  7033   0 10:27:44 console     0:00 add_drv -n -m * 0600 root 
sys iscsi
     root  7177  7150   0 17:28:54 pts/1       0:00 grep 7033
s10u7-base:/# truss -p 7084
^C^C
Directory /d0/tmp was mounted into the domU via NFS, if this matters.
Interfaces are configured on an etherstub.
H/W Platform is
System Configuration: Sun Microsystems Sun Fire X2100 M2
BIOS Configuration: Sun Microsystems S40_3A21 10/30/2008
BMC Configuration: IPMI 1.5 (KCS: Keyboard Controller Style)

Does this ring a bell anywhere?
Any advise is highly appreciated!
Thank you, Nils
