I have a Z3735F baytrail tablet running Debian 8 with a 1 month old linux-next kernel. I've lowered the i915_max_freq to 345 MHz, and achieved stability that way. No freezes since then. The Z3735F GPU has a base freq of 311 MHz, so I am pretty close to that. I have also patched the kernel source with a few baytrail sdhci related patches from: https://github.com/hadess/rtl8723bs/tree/master/patches -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1453298 Title: 8086:0f31 Xubuntu freeze once a day To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1453298/+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
