I have STL2 machine, if I compile kernel (2.4.18) with ACPI I got:
[...] (I hope this is OK, I write it down from monitor ;-) )
ACPI: Core Subsystem version [20011018]

<0> Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
[...]

without ACPI there isn't any problem, with ACPI in (I think) 50% starts.

My system:
Intel STL2 with 2xPIII 1 GHz, I can enclose details (lcpci, etc.)
I can't do more tests (it's a production machine).
