You're seeing this with the boot iso, right?

Next time, when presented the opportunity, press ESC and get to the grub menu.  When you get there, press 'e' for edit, then edit the line with "unix" toward the end.  After "..../unix" and before any other flags, insert "-k".

You will boot with kmdb, and when it panics, you will enter the kernel debugger, where you can show this list the panic stack with mdb's "$c" command.

Please share that stack with the list.

THanks,
