Oh my god! This is why my $4,000 laptop has been crashing!?

Only if you have a 10th generation Ice Lake, which is the 2020 Air and 2020 13" Pro. The 16" has a 9th generation Coffee Lake and does not seem to be affected, so if you have this or an earlier laptop it would have to be something else. Read the whole thing... it's a ride. Serious WTFBBQ with a side of potato salad. Once Apple and/or Intel notices this there will probably be a microcode update. Until then if AWS or some other host fields Ice Lake based server cores you may be able to crash the VM host by starting up a Jetbrains IDE in a VM. LOL The parent post on Transmeta QA shows that obscure bugs causing wacky edge cases are not that rare. It's a function of the complexity of modern chips, especially the X86 lineage with its crazy variable instruction widths and legacy cruft. You can, I think, still boot 16-bit DOS and Windows 3.1 on them! ARM is intrinsically less prone to this due to simpler pipelines and less cruft, but ARM64 chips are still pretty complex. Any real world chip that has been around for a while is going to grow some hair on it. ARM has some shag but X86 is hairier than a wizened yak. RISC-V is clean... for now. But there are no really high performance RV chips. I wonder though... do they not fuzz chips? How do these things escape QA at a serious experienced house like Intel? I can understand obscure security issues slipping by but an a hard crash?

    Also happens on the Surface Pro with the same chip, so unlikely.

      There was a bug in the Sony Picturebook w/ a Crusoe in it, I don't remember what the bug was. To isolate it, I drove over to Fry's Electronics and replicated the same exact bug using the Intel flavored Picturebook on the display counter :)

  I wonder if Rocket Lake is going to have that bug as well.
