There is no visible log/feedback produced so users tend to give up and move on to other operating systems hence there isn't any tips regarding this workaround except couple of pages. I can boot fine with acpi_osi= argument. I tested latest RC (using Ubuntu 16.10) however it effects every kernel out there, on this particular machine. I can provide more details, even a root shell if it can help. More possible machine details etc. are at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848445 Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848445/comments/6 ------------------------------------------------------------------------ On 2019-10-18T06:05:14+00:00 ilgaz wrote: Apologies for typo: It isn't Ubuntu 16.10 which I tested, it is 19.10.
