the bugfix in the new kernel 2.6.15-25-386 for Bug 39315 obviously didn´t work for acer travelmate (maybe also aspire) laptops. see Bug 39315. i´m not sure, if the last bugfix fixed the problem of bug 39315 because by now there is no feedback from anyone. just some users report, that the problem is still not fixed.
