Hi Evgeny,
I didn't try the latest coreboot master in a while as I wanted to rule out hardware damage as a possible cause and reflashed the Lenovo OEM BIOS.
From what I recall, the last coreboot master I tried resulted in crashes without your patch.
I intend to run following tests with the latest coreboot master (I'll note the commit hash and use the same commit for all of my tests) and SeaBIOS as payload (blobs will be extracted from the Lenovo OEM BIOS v2.81):
1. fully blob'ed (vgabios, ifd, me, gbe) 2. libgfxinit instead of vgabios 3. fully blob'ed with the me shrinked 4. libgfxinit instead of vgabios with the me shrinked
If all tests pass, I'll try the same tests with your patch. If a test without your patch applied fails I'd argue that something else is to blame.
I'm unsure on how to provide the µCode patches, i.e. integrate them in coreboot or have them patched by Linux.
Since watching videos on Firefox and compiling the coreboot toolchain seem to reliably crash the laptop I'll use those to try and provoke a crash. I'm open to suggestions for other "crash provoking workloads".
I'm also considering reinstalling the OS (Debian Buster 10.2 with Gnome3) to rule out some weird configuration as a possibility.

Hi, Lars.
Update: I flashed the original Lenovo BIOS v2.81 (with keyboard EC mod) and the issues seem to be gone.
Do you have any freezes/crashes while running latest coreboot (from master) without the HT patch? _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-leave@coreboot.org
