No, the malloc() just happens to be the first line shown -- the actual
line indicated by the debugger is in the middle of the listing (#336).
(not that it makes much more sense though it seems)
Note this same kernel boots and runs fine on a fairly wide variety of
other hardware (and virtual machines), including an Asus motherboard I
happen to have with a similar chipset (Intel 6300ESB) but of course with
a different BIOS. Removing "options PCIBIOS" also makes it boot fine on
the hardware in question, of course, as that's what enables the code
path seen in the backtrace, as well as being the pertinent difference
between the working INSTALL_LARGE kernel and the crashing GENERIC.MP.
There's nothing really very unusual about this embedded server board
except for its BIOS, and the fact that it doesn't seem to even have a
keyboard controller (for Windoze they rely on USB keyboard/mouse).
