Red Hat Bugzilla – Bug 238054
Toshiba Tecra M2 will only boot with acpi=off; tries to load ibm_acpi?
Last modified: 2007-11-30 17:12:03 EST
Description of problem:
Trying to boot rawhide on a Toshiba Tecra M2 causes it to hang just after
displaying some errors about ibm_acpi (I don't know why this is being loaded).
Booting with acpi=off seems to work around the problem.
I would attach a log, but somehow this error doesn't make it that far. Let me
know if you need a screenshot (or any other information).
Version-Release number of selected component (if applicable):
The same problem happens on my Gateway M255 Laptop with F7T4. All of the FC6
kernels have worked fine thus far. If there's any more information I could
provide, please let me know.

It seems to me that if i add blacklist ibm_acpi to /etc/modprobe.d/blacklist it
works _sometimes_ other times it hangs with a similar error on loading plain old
here's a link to my smolt profile for more hardware info:

Dmesg output showing error
I just found a kernel which works... It is 2.6.21-1.3142.fc7 posted on the
-devel mailing list for iwlwifi stuff. Interestingly, this still has the same
problem with the ibm_acpi module, except it keeps booting after the module dies.
After it boots ACPI _seems_ to work as far as i can tell so far (5 minutes).
Anyway, I'm attaching the dmesg output with the acpi error present.

Untested patch to fix the oops
Reported this bug upstream.
I apologize for jumping the gun before and reporting that that kernel worked. It
worked for one boot and is now as non-working as the others (why it works
sometimes still baffles me) However, the one time it did work It allowed me to
get the dmesg output so hopefully that was good. I'll try that patch out later
tonight and report what i find. Thanks!
Ok, I just built a kernel patched with the above patch and rebooted 4 times. No
error or lockup at all. It seems to have fixed it.
applied to cvs, will be in next build.
