mm.. There are known scheduling-inside-spinlock bugs in the PPP
driver.  Paul is working on these at present.  This will cause
deadlocks on SMP.  Anthony seems to be running uniprocessor, but
bad things could still happen.

It'd be interesting to enable the local-apic-on-uniprocessor
and io-apic-on-uniprocessor options, then boot with the
`nmi_watchdog=1' LILO option, see if you can get an NMI oops
backtrace.
