Hep me! ksmserver crash

This started after an update Friday. Get the login screen, system accepts password, progress bar shows for about 1/3 of the way, then get the dialog box about ksmserver crashing. I've done both "report crash" and "create backtrace" both of which cycle me back to the login screen. I pull packages from here: deb http://mirror.xcer.cz/trinity-sb trusty deps-r14 main-r14 Stuff I don't understand from the logs: Feb 9 11:01:47 toto3 kernel: [ 0.008000] tsc: Marking TSC unstable due to check_tsc_sync_source failed Feb 9 11:01:47 toto3 kernel: [ 0.920132] ioapic: probe of 0000:00:05.4 failed with error -22 Feb 9 11:01:47 toto3 kernel: [ 4.348917] fglrx: module verification failed: signature and/or required key missing - tainting kernel Feb 9 11:01:48 toto3 failsafe: Failsafe of 120 seconds reached.
