I am having a similar issue on my SunBlade 1000, but mine happens
frequently enough as to make the machine unusable as a workstation.
2 x 1.2ghz cpu
2 x xvr1000
2 x 73gb fcal drives
sun crypto 1000
If anyone is interested, I do have an OpenBSD 4.4 DMESG of this box
I did double check the obp, and I do have revision 17 of the patch
It is a fresh install of Solaris 10u8 with all patches allowed by a
non paid sun account (no paid service contract).
I have disabled power management, and that appears to have little or
no effect on the system spontaneously rebooting and reporting the
"Fatal Error reported by PCI-PBM" . Occasionally the letters CPMS
append the error, but not always.
I have seen this error posted as having originated on a SunFire 280R
as well, so from what I understand, it can not be something
framebuffer, at least the XVR-1000, related since the XVR-1000 does
not even fit in the 280R with the RSC being installed.
To answer some other posts I have seen, there is a qlogic "card" in
this machine, but it is builtin to the motherboard. There is also a
SCSI card, but again, it is builtin to the motherboard.
