As soon as a disk is present in the first slot of the Promise adapter the 
kernel locks during boot as shown below (no sysrq, no led, nothing)

[insert guru meditation here]

It's 100% reproductible with 2.4.17-pre8/-rc1 and RedHat's 2.4.7-10.
The disks are all the sames. Swapping them doesn't change anything.
Tried RH 2.96-98 as well as egcs-1.1.2 -> lock.
Disabled APM, ACPI, SMP (APIC+IOAPIC enabled) -> lock.

/proc/pci and /proc/cpuinfo follow.
Attached is a "normal" complete boot dmesg (I simply removed the disk).

If it isn't the expected behavior before refund, I'm open to
suggestions.

Thanks.
