Re: PCIVERBOSE causing kernel stack overflow during boot - why?

[Paul Goyette <paul%whooppee.com@localhost>]

Just as an added experiment, can you try to boot the non-PCIVERBOSE 
kernel, and at the boot prompt enter

	load pciverbose

before actually booting?

As far as getting a back-trace, you could set DDB_COMMANDONENTER="bt" in 
your config file ....

The dmesg looks interesting, especially with that strange pci9 bus.  My 
machine has a similar "management devices" pci bus.
