That's just the workaround until a fix is available for your CPU, if I understood correctly.

No, that's not what I meant. In the past, Intel's microcode updates have simply disabled the broken functionality as an official solution.

You specifically said the fix might be to permanently disable HT.

The TSX situation was indeed unfortunate, I have one of the affected CPUs. But it was a new feature that was broken, not something that used to work, so the bug's impact was less serious, and disabling the feature didn't have too much of an impact.

Contact your laptop OEM.

Have you ever had to do this?

The Dell XPS 9350 (Skylake) has numerous issues with GPU noise, USB-C compatibility, wifi reliability - Dell don't care unless your consumer laws are strong enough to make them care.

No but dell had a 30 day full refund policy. Did those bugs not start until day 31?

TBH, everything was covered by warranty other than the coil whine and wifi - by sticking to one particular driver version you can avoid many of the wifi issues. Not everyone has had the USB-C problems and it's gotten a little better with the most recent updates.
