Okay, I'll download a regular Ubuntu 14.04.2 LiveCD and use it to prepare the diagnostics info. I won't be using a modified BIOS at that time.
I'm currently switching between the latest official and my custom BIOS. The latest BIOS 214 is known to have caused similar behavior in WIndows 8.1, and earlier BIOS versions are sheerly unusable because they cause a shutdown every time AC is unplugged while CPU is under strain (that's why they had to make the 214 version) BTW, when running on AC, Kubuntu 14.10 Plasma Next boots some three seconds faster off an SSD with my modified BIOS, as compared to the vanilla BIOS. Also no shutdowns so far. Prompts me thinking it was buggy CPU microcode that under certain conditions provoked abnormal power consumption peaks / some other undesirable effects that backfied when running on low battery. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1446027 Title: SNA acceleration causes sudden shutdowns and corrupts CMOS data on the the Asus UX21E ultrabook on a wide variety of kernels since at least Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1446027/+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
