I have the same thing on my thinkpad R40e. I found this bug on kernel.org so it looks like it isn't a ubuntu specific issue.
http://bugzilla.kernel.org/show_bug.cgi?id=8246 The good news is that as a workaround you can add ec_intr=0 to your kernel options. This worked for me. My system is back at full speed and battery monitor etc work fine, though I have to admit that I'm not sure what this option changes, but it's a better option than blacklisting the battery and ibm_acpi modules that I was doing before. -- loading ACPI modules and starting HALd took too long time https://bugs.launchpad.net/bugs/107516 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
