Issue #121 has been updated by Evgeny Zinoviev.
On my x230 with gentoo, with recent kernel the situation has worsened significally. If on 5.x kernels it worked somewhat stable (I had crashes maybe once in a month or so and maybe it wasn't even coreboot related), now I after upgrade to 6.1.12-gentoo and it freezes like twice a day.
This might be completely bug-121-unrelated, but limiting max cstate to c3 seems to fix the issue, so I decided to report here anyway... can anybody confirm the same? I mean that the newer kernel == more freezes/crashes
---------------------------------------- Bug #121: T520: Hangs in OS https://ticket.coreboot.org/issues/121#change-1466
* Author: Julz Buckton * Status: New * Priority: Normal * Start date: 2017-06-09 ---------------------------------------- I have been running coreboot since 2017.04.15 and have experienced hangs ever since then. It was suggested by folk on the IRC that I run memtest to check for incorrect raminit causing errors, however I have run memtest for 12 hours straight with no errors.
Due to the ambiguous nature of the hangs (immediate freeze with no warning signs, audio gets stuck repeating the last 50ms or so of noise, not sure what this effect is called) I don't have much useful information other than the .config and dmesg. However one thing I can say with high confidence is that the hangs occur significantly more frequently in Linux (*buntu distros) than Windows 10. Within an hour of launching Linux a hang is likely, whereas Windows typically runs for many hours before a hang occurs. I considered this an insignificant anecdotal anomaly at first but over the course of the nearly 2 months I have been running coreboot it seems to be a solid trend. The hangs occur anywhere, typically during mere desktop usage or basic web browsing.
Additionally there is another form of hang I experience where the screen goes black except for some sort of graphical corruption down the left side (http://i.imgur.com/4zWrlpX.jpg), whether this is related to the more common total freeze hangs I don't know but I figured I should include it nonetheless. These hangs only occur about 1:20 compared to the regular hangs.
