 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  
 BIOS
 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
 INVARIANTS).
 Btw running a kernel without INVARIANTS on this box is no problem for me ;-).
 
 HTH,
    Martin
 
 P.S.: Haven't seen the malloc panic with 6.x, but I did only 2 panics...
