Hi All,

We've tried booting 2.2 linux on two CPX2000 systems with the same result
ie. scsi failures.  The led on the cdrom flashes while it's being tested, if
that helps anyone recognize the problem.  Has anyone out there been successful
booting the CPX2000?  It is MCP750 based compact PCI.  The console follows:
