i have a new laptop (Dell Latitude C610) running 2.4.18-rc4. when i built the
new kernel, i thought i would amuse myself by turning on IO-APIC. the
configure.help entry claims that even if you don't have an IO-APIC system, the
kernel will still run without problems.
this is definitely _not_ the case on this laptop. i get a hard lockup, at a
random time after booting this kernel. it seems very reproducible if i enable
the network interfaces (eg, it happens within moments), but even if i don't
enable them it will still lock up (within a few minutes).
any suggestions? is configure.help lying to me making this idiot user error?
google searches didn't turn up anything recent about problems here...
regards,
josh fryman
PS>
if it's useful, below are /proc/pci and dmesg after a successful (no IO-APIC)
kernel boot:
