Open
opened 1 month ago by raghavgururajan · 3 comments

With libreboot v20210522, the device turns-off abruptly, whenever CPU load is high. Examples of high CPU load are compiling a program, heavy browsing etc. This happens with or without microcode update [1].

This issue doesn't happen with libreboot v20160907, with or without microcode update [1].

sorry, no, i accidentally posted that here instead of the intended place

as mentioned on irc, just send me your board

i will investigate it directly. i think this is just your board. i haven't seen this with any other x200t. i will pay for your shipping cost to send the board
