This patch fixes the problem for me, although I suspect that it probably re-breaks CVE-2012-0946. Hard to tell with a closed source project. :(
Anyway, I slipped in a printk to print the offending offset and size. On a GeForce 7300GT (~2006 iMac) it looks like something in the driver is trying to map 0x1000 0x1000 (which is explicitly checked by the IS_BLACKLISTED_REG_OFFSET macro). I have no idea what registers are in there, but for that system the ability to create the memory mapping is crucial to restarting graphics during resume. I wonder if this will fix the other people who can't even get Unity3d started, but that's pure speculation. ** CVE added: http://www.cve.mitre.org/cgi- bin/cvename.cgi?name=2012-0946 ** Patch added: "revert-295.40-security-fix.patch" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/983323/+attachment/3081741/+files/revert-295.40-security-fix.patch -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/983323 Title: [regression] Corrupted screen and sluggish performance after suspend with 295.40 drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/983323/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
