I have a similar setup: Mainboard: T420 CPU: i7-3940XM RAM: Corsair Vengeance 16 GB DDR3 1600 MHz (CMSX16GX3M2A1600C10) iGPU: Intel HD Graphics 4000 dGPU: NVIDIA Quadro NVS 4200M Coreboot version is CBET4000 4.16-1069-gf4905da14c using MrChromebox's old "corebootpayload" branch as payload (which is now deprecated, I think). Intel ME was stripped. Coreboot config is attached. With intel_idle.max_cstate=2 the system is stable. Any higher value results in the freezes as described above (sometimes with the glitch on the left side of the screen, sometimes without). It's weird how intel_idle.max_cstate=4 doesn't work for me. If anyone is still looking into this, I would be happy to help. ---------------------------------------- Bug #121: T520: Hangs in OS https://ticket.coreboot.org/issues/121#change-1455 * 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. ---Files-------------------------------- config (20.7 KB) dmesg.txt (57.3 KB) cbmem-raminit.txt (62 KB) lspci.txt (29.6 KB) cpuinfo.txt (3.94 KB) defconfig (1023 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.
