The main point of this bug: please don't release a new stable kernel before a good patch is produced for the mainline, or some other resolution becomes available at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/554569 The number of X2xxx ThinkPad users is significant. The point is, we do our best to solve bugs before we stabilize a kernel, but we cannot anticipate any bugs that appear after a stable request, nor can we expect to have zero bugs. We make sure wide ranging bugs don't exist as well as critical security bugs. Ok, I was making my previous statement not being aware of gentoo-sources-2.6.33-r2 being stabilized at the very same moment :) My concern was 2.6.34 and I was asking devs to keep an eye on the blank screen bug. Kernels prior to 2.6.34 have another issue with USB not functional after suspend/resume (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/566149). Not sure if it is worth filing here though. Sorry once again - that patch to 2.6.34 actually worked for me. Help me out so I am clear. Bug is on 2.6.33 and 2.6.34. Is this the patch that fixes the issue for both versions? http://bugs.freedesktop.org/attachment.cgi?id=36483 You can open a separate buug for the usb problem if you like.
