Description of problem:
While booting to enterprise kernel on a pe6400 w/ bios A09,a perc3dc raid 1
container and 5GB of memory, kernel panics. Flash back to A08 and
enterprise kernel loads regularly. Flash to A09 and kernel panic returns.
UP and SMP kernels load w/ bios A09 just fine.
Attached is serial output of enterprise kernel bootup and panic.
Steps to Reproduce:
1.Install fairfax beta2 on a 6400 w/ over 4GB of memory and bios A09. It
is possible that the error depends on the presence of perc3dc.
2.Reboot and choose enterprise kernel to load
Actual Results: Kernel panic
Expected Results: Normal bootup

Serial console output of enterprise kernel panic
Is this with grub or with lilo ?
It seems the initrd is corrupted somehow

- BIOS-e820: 0000000100000000 - 0000000140000000 (usable)
+ BIOS-e820: 0000000100000000 - 0000000140102000 (usable)
is there any way to be certain how much memory there REALLY is ?
This defect is considered MUST-FIX for Fairfax.
Dell test BIOS T42 fixes this, and the USB failure too. This will become an X-
rev BIOS, and eventually released as an A-rev BIOS.
