Gotcha! (see bug http://65.172.181.4/show_bug.cgi?id=1185 for reference)
2.4.23-pre3 (with some patches): first, the messages are printed:
acpi_power-0363 [28] acpi_power_transition : Error transitioning device [CFAN] to D0
acpi_bus-0496 [27] acpi_bus_set_power : Error transitioning device [CFAN] to D0
acpi_thermal-0549 [26] acpi_thermal_active : Unable to turn cooling device [c12d24a8] 'on'
And then, 4 seconds after:
ksymoops 2.4.9 on i686 2.4.23-pre3-xcs. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.23-pre3-xcs/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
