the "buggy and outdated" bios seems to be mostly the same as the one that came with the machine (207), the changelog only mentions something about disk power management; I updated it, anyway:
UX302LG.210 06/16/2014 This seems to be a GPU lockup, though, when it happened the day before yesterday I was looking at something on youtube, and the audio (over Bluetooth, no less) kept going until the end of the clip; when attempting to switch to a text console I saw briefly something along the lines of "gpu queue underrun"; the keyboard is useless, though, apart from the Magic SysRq combinations. Nothing gets logged, btw (and the disk is fine, syslog records the kernel messages when I'm doing the SysRq dance (sync, remount read-only, reboot). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1402401 Title: Xorg freeze when switching to text console and back Status in linux package in Ubuntu: Incomplete Bug description: Sometimes the computer becomes unresponsive after switching to a text console and back; this seems to be an Xorg and / or kernel driver crash (there is a backtrace in dmesg that seems to be from Intel drivers). The rest of the system worked fine, I could SSH into it and restart Xorg. I had an (html5) Youtube video playing in Firefox when the lockup happened, I'll try to see if that was the culprit (I switched a few times to text console and back after restarting X and all was fine, but I didn't have a video running) ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: xorg 1:7.7+7ubuntu2 ProcVersionSignature: Ubuntu 3.16.0-28.37-generic 3.16.7-ckt1 Uname: Linux 3.16.0-28-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 BootLog: * Setting up X socket directories...
