Zones not booting - failed to create devlinks: Interrupted system call

Question

I just installed the latest 10_Recommended cluster with 118833-36 kernel patch and now my zones won't boot. I get the error:
(root)Yes Master?> zoneadm list -iv
ID NAME STATUS PATH
0 global running /
- samba installed /export/home/zones/samba
- web installed /export/home/zones/web
- dhcp installed /export/home/zones/dhcp
- dns installed /export/home/zones/dns
- vs1 installed /zdata/zones/vs1
- dss installed /zdata/zones/dss
- test installed /zdata/zones/test
(root)Yes Master?> zoneadm -z test boot
failed to create devlinks: Interrupted system call
console setup: device initialization failed
zoneadm: zone 'test': could not start zoneadmd
zoneadm: zone 'test': call to zoneadmd failed
Also, running devfsadm or drvconfig;devlinks from the global zone will core dump.
Any ideas..??

First, you gotta change your prompt to something less embarrassing when you post to a public forum :)
I'd forget about the zones problem and focus on why devfsadm core dumps -- that's the core of the problem (no pun intended...no, really!).
First, review the install logs of all the patches installed during the recent service (/var/sadm/patch/*/log). Even if they all show a good completion, check the messages they generated, sometimes they have errors that aren't bad enough to cause a complete failure of the patch. The KJP (118833-36) is probably a good one to start with.
Next I'd "truss" the devfsadm command while it core dumps then get a stack trace of the core (run "adb <corefile>" and type "$C" -- that's old school, I'm sure mdb is much cooler...).
Throw some of the strings from those against sunsolve and see if something sticks.
Good luck!
