Running this also works (disabling intel_idle.max_cstate=1 on grub).

[Bug 1833169] Re: intel_max_cstate is needed with baytrail to aviod hangups
Hi, intel_idle.max_cstate=1 DOES provide a workaround (no freezes, but high battery usage). The patch is going to get into 5.2 merge window apparently, so I will test it in that moment (in 4 weeks). Perhaps I will compile a kernel with the patch, but is difficult with this hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833169 Title: intel_max_cstate is needed with baytrail to aviod hangups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1833169/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Jaime Pérez, please answer all of the following: 1) Have you tested an upstream kernel containing the proposed commit, or tested the commit to confirm it resolves the issue for your hardware? If not, one may test the relevant usptream kernel via: https://wiki.ubuntu.com/Kernel/MainlineBuilds or testing only a patch via: https://wiki.ubuntu.com/Kernel/KernelBisection#Testing_a_newly_released_patch_from_upstream 2) Does the following kernel parameter you are using provide a WORKAROUND for your hardware: intel_idle.max_cstate=1 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833169 Title: intel_max_cstate is needed with baytrail to aviod hangups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1833169/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
