Some information that maybe relevant: The blacklist used to be broader but was restricted by https://kerneltrap.org/mailarchive/git-commits-head/2008/9/7/3217784 The discussion is in particular here: http://lkml.indiana.edu/hypermail/linux/kernel/0809.0/0316.html which states that the problem for which one didn't want to blacklist was a: System Information Manufacturer: LENOVO Product Name: 076836U Version: 3000 N100 There seems to be many various versions of that Product Name http://smolts.org/reports/view_profiles?profile=+3000+N100&search=Submit I wonder if there are other versions affected by this "regression". For example https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/86820 points to http://launchpadlibrarian.net/6494256/dmidecode Manufacturer: LENOVO Product Name: 0768B9G Version: 3000 N100 which is probably also affected It would be nice if the message that displays "failed to resume active multiplexor, mouse won't work." could also print out the relevant dmi information. That way one could use google to find potentially affected systems :) Cheers, Jerome -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
