Output of dmidecode on laptop none

Description Alexandre Oliva 2002-12-22 10:11:23 UTC
/proc/acpi does not exist on my ssytem, and trying to modprobe some of the
drivers inside /lib/modules/2.4.20-2.2/kernel/acpi (e.g., ospm_battery) may even
cause the kernel to print an oops message.  Also, apm says apm support is
disabled in the kernel, so...

I can no longer suspend, hybernate or even blank the screen of the laptop.  The
Fn key sequences that I used to use for these operations no longer work, but
other key sequences still work, so I suppose it may be related with the lack of
acpi/apm support in the kernel.  Is this assumption correct?

Comment 1 Arjan van de Ven 2002-12-22 11:25:02 UTC
please try acpi=off on the kernel commandline and attach dmidecode output to
this bug

Comment 2 Alexandre Oliva 2002-12-22 20:47:11 UTC
Created attachment 88857 [details]
Output of dmidecode on laptop

acpi=off ``fixes┬┤┬┤ it, indeed.	Thanks!

Here is the oops generated when loading the acpi_battery module
(beta3/redhat-release-8.0.92-2 kernel-2.4.20-2.2):
