Comment 30 for bug 430361

As I commented in bug 346303, a kerneloops update was issued last night (see bug 471137) that effectively neuters kerneloops by default for karmic, so you should stop seeing these warnings once you apply the update. (It can be re-enabled by editing /etc/default/kerneloops).

What's happening here is that kerneloops is monitoring the kernel log looking for output that looks like a kernel oops (hence the name) or was generated by a BUG_ON() or WARN_ON() call. In this case, it's a false positive in that the reported message starts with "Warning" which is what kerneloops triggers on to look for an invocation of WARN_ON(). The thinkpad_acpi kernel code that emits it should either be fixed to do a proper WARN_ON() if it's warranted or the string should be changed to "Alert" or something similar.
