This is known to some extents, for R50e we have this in the whitelist: /* R50e needs not yet implemented save_video_pci_state :-( { "IBM", "1834*", "", "", UNSURE }, { "IBM", "1842*", "", "", UNSURE }, { "IBM", "2670*", "", "", UNSURE }, */ and your machine probably also falls into the same category. However, _i_ consider this to be either a driver or a pci-subsystem kernel bug which really should be solved there. If somebody really thinks we should work around this in userspace, he has to either use a custom script and wrap this around "s2ram -f" or send a patch that implements this cleanly in s2ram. At least this is my opinion on the matter :-) -- Stefan Seyfried | "Please, just tell people QA / R&D Team Mobile Devices | to use KDE."
