Update: I flashed the original Lenovo BIOS v2.81 (with keyboard EC mod) and the issues seem to be gone. Additionally the RAM now runs with 2133MHz without the system freezing and I also can compile crossgcc-i386 with CPUS=8 without issues. Watching videos on YT using Firefox works, too.
The Intel ME is also back. Could there be an issue with the system initialization done by the Intel ME which does not occur if the Intel ME is fully functional?

There are some similarities: the system freezes (i.e. UI is unresponsive, you have to hold down the power button to reset the system) and sometimes it outright crashes into a reboot. The crashes seem to trigger when the CPU is running high loads - take note though: with your HT option patch I could run the stress tests of the CoreFreq (https://github.com/cyring/CoreFreq) tool without crashes / freezes but I only tried for a couple minutes.
I do get crashes sometimes when I compile crossgcc-i386 (CPUS=$(nproc), with and without HT enabled through nosmt in the GRUB config) but more often make runs into some error and simply won't compile the sources (I notice a certain tendency towards the gcc compilation) - I would usually recompile but it now seems to be more persistent. There seems to be also a good chance to crash when the CPU isn't fully loaded but multiple applications are open - most notably Firefox when watching Youtube videos and doing something in another application / Firefox tab.
Originally I was running coreboot v4.6, then changed to v4.8.1 then v4.9, then for some time to master (blobs were based on BIOS v2.79, me disabled and neutered). I'd argue that the issues started appearing after my switch to v4.11. However I can not rule out hardware issues, as I overtightened the screws on the heatsink last time I was working on my T430 - maybe the overtightening caused physical damage to some solder joints on the CPU / socket.
Here are some system stats:
CPU: i7-3840QM, TurboBoost is disabled through the intel_pstate driver to prevent my laptop from melting RAM: HyperX 2x8GB 2133MHz DDR3 1.35V HX321LS11IB2K2/16, it runs at 1600MHz (the "ignore fuses" option isn't set) though as the system would freeze shortly after logging in Mainboard: no dGPU variant OS: Debian 10.2 64bit with the default Gnome3 DE Mods: the 7 row keyboard mod and the FHD screen mod (maybe that is why I didn't see any visual artifacts) coreboot blobs (ifd, me, gbe): based on BIOS v2.81, me is neutered and disabled
I managed to capture following dmesg, when the system soft locked while Firefox was open and I managed to switch to a tty. If I recall correctly there was some audio repetition.

Have you got any logs? Do these crashes/freezes look like https://ticket.coreboot.org/issues/121? _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-leave@coreboot.org
