Here's more about my problem: it seems 2.6.8-rc3-mm1 sometimes manages to
boot here. Even so, kacpid completely hogs the CPU. dmesg and debug output
is at http://hell.org.pl/~sziwan/2.6.8-rc3-mm1.report (300 kB), DSDT is at
http://hell.org.pl/~sziwan/l3800c.dsl. Note the odd thermal zone output
(did somebody mention TZ problems?). Call trace below.
Best regards,
