Hot CPU after hibernate (Dell Inspiron 4100)
I'm trying to get the hibernate package working on my Dell Inspiron
4100. So far, everything appears to be working fine, with one
exception: after resuming from hibernate, the system shows all the
signs of high CPU load --- the CPU temperature keeps creeping up until
both fans are running. This persists until I reboot the computer. top
doesn't show anything using much CPU, so I'm assuming something more
nefarious is happening here. Any ideas?
Let's see, information you'll want... I'm running version 1.12-1 of the
hibernate package, and a stock Debian 2.6.12 kernel (package
linux-image-2.6.12-1-686, version 2.6.12-5, which AFAIK means no
suspend2 and ACPI rather than APM). I've attached a copy of my
hibernate.conf and the outputs of lspci -v and lsmod. i8kctl prints:
1.0 A03 8PMM611 52 0 0 0 0 1 0
Anything else? Something from /proc/acpi, perhaps? TIA.

### Choose your Suspend method. You currently have 3 choices:
###
### suspend2 Software Suspend 2 (requires kernel patches from
### http://www.suspend2.net/)
###
### sysfs_power_state Uses /sys/power/state to suspend (activates pmdisk
### on kernels < 2.6.8, or vanilla swsusp otherwise).
###
### acpi_sleep Uses /proc/acpi/sleep to activate swsusp, or other
### ACPI sleep state supported by your machine.
###
##############################################################################
### suspend2 (for Software Suspend 2)
#UseSuspend2 yes
#Reboot no
#EnableEscape yes
#DefaultConsoleLevel 1
#Compressor lzf
#Encryptor none
# ImageSizeLimit 200
## useful for initrd usage:
# SuspendDevice swap:/dev/hda2
## Powerdown method - 3 for suspend-to-RAM, 4 for ACPI S4 sleep, 5 for poweroff
# PowerdownMethod 5
## Any other /proc/software_suspend setting can be set like so:
# ProcSetting expected_compression 50
## Or traditionally like this:
# Suspend2AllSettings 0 0 2056 65535 5
## Or even from the results of hibernate --save-settings with this:
# Suspend2AllSettingsFile /etc/hibernate/suspend-settings.conf
## For filewriter:
# FilewriterLocation /suspend_file 1000
# VerifyFilewriterResume2 yes
# ProcSetting userui_program /usr/local/sbin/suspend2ui_text
### sysfs_power_state
## To use /sys/power/state to suspend your machine (which may offer
## suspend-to-RAM, suspend-to-disk, standby, etc) comment out all the options
## above for Software Suspend 2, below for acpi_sleep, and uncomment this line.
## You may replace mem with any one of the states from "cat /sys/power/state"
UseSysfsPowerState mem
PowerdownMethod shutdown
### acpi_sleep
## To use ACPI to suspend your machine (via /proc/acpi/sleep), comment out
## all the options above for Software Suspend 2 and sysfs, and uncomment this
## line. The number refers to the ACPI sleep state - 3 is suspend-to-RAM and
## 4 is suspend-to-disk.
# UseACPISleep 4

### Scriptlets
### Scriptlets provide support for doing all sorts of things before and after
