Classification: Development

Status: ACCEPTED
Severity: critical
Priority: P2
Component: PAD
AssignedTo: eric.saxe at sun.com

ONPIT reports:
Several x86 systems and DomU guests are panic'ing with
panic[cpu0]/thread=fec25460: BAD TRAP: type=6 (#ud Invalid opcode)
rp=fec406fc addr=fec43388
#ud Invalid opcode
addr=0xfec43388

Unfortunately, as most of the systems seeing this are DomU guests
the first couple of lines are corrupted and lost, this partial stack
is from a Pentium4 system also experiencing the problem.
This has been seen several times in the respin build also on similar
systems.
