It's the same hardware (except now larger IDE disks) that produced the  
original panic. An Intel BX440 based motherboard, the Asus P2B-S. The  
is the latest 1013.
ACPI does not work with this board, Linux automatically disables it at boot
with a message like "P2B-S Rev. 0 motherboards have a known PCI  
interrupt routing problem". However APM works fine (except with a  
FreeBSD kernel with
Btw running a kernel without INVARIANTS on this box is no problem for me ;-).


P.S.: Haven't seen the malloc panic with 6.x, but I did only 2 panics...
