Description of problem:
During bootup, immediately after the message "Enabling swap" appears,
the system will power off. If I change /etc/grub.conf to boot with
ACPI=off, the system starts up just fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot the system
Actual Results: The laptop powers off right after (or during) the
time swap is enabled.
Expected Results: It should have continued booting up :)
This laptop was running Fedora core 1, and I upgraded it to FC2-test1
by making a yum repository on another machine and running "yum upgrade".
I just completed a fresh install (reformatted everything to make sure
there weren't problems related to the upgrade) and the problem
persisted. Disabling ACPI still allows it to boot properly.
I can reproduce on a Dell Latitude CPx laptop (model PPX, Latitude C
family). I've also just completed a fresh install of Fedora Core 2 test1.
When booting with acpi=off evrything works just fine.
When booting with acpi=on (the default) the laptop powers off early
during the boot process. Before it powers off I see the following
message on the console:
Critical temperature reached (-296 C), shutting down.
I should have mentioned that I'm seeing this on a Dell Inspiron 4000,
model PP01L. I didn't see the "Critical temperature reached" message,
but that may be because it shut off too quickly.
Now running kernel-2.6.3-116 and the problem has been resolved! Thanks!
