Red Hat Bugzilla – Bug 431494
Kernel goes into thermal shutdown very easily
Last modified: 2008-10-22 17:41:03 EDT
Description of problem:
I've got an IBM X60 laptop, running x86_64 Fedora 8. Recently, if I try and run
anything CPU-intensive for more than a few seconds, the kernel has been going
into thermal shutdown mode extremely easily.
There seems to be a longer-than-before lag between the CPU getting busy and the
fan kicking in, too. I realise this is all rather non-specific, but I don't
know what information would be useful to you.
When the system shuts down, I get the following message:
Critical temperature reached (128 C), shutting down.
This doesn't match the results of looking at /proc/acpi/ibm/thermal or
/proc/acpi/ibm/fan. The CPU reading from thermal is below 80C when the shutdown
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start a kernel build or something similar.
2. Wait less than a minute.
Please provide the output of the 'lsmod' command...

Here you go.
Oh, and here's /proc/cmdline for good measure.
ro root=LABEL=/ quiet usbcore.autosuspend=1
Can you also attach the boot messages? (the file /var/log/dmesg)
The information we've requested above is required in order
to review this problem report further and diagnose or fix the
issue if it is still present. Since it has been thirty days or
more since we first requested additional information, we're assuming
the problem is either no longer present in the current Fedora release, or
that there is no longer any interest in tracking the problem.
Setting status to "CLOSED: INSUFFICIENT_DATA". If you still
experience this problem after updating to our latest Fedora
release and can provide the information previously requested,
please feel free to reopen the bug report.
Thank you in advance.
