Not by us, at least. The processor model, firmware or microcode might
limit the availability of Intel TSX.
But it took quite a while for out-of-the-box Skylake BIOSes (i.e.
installed to the motherboard in the factory) to actually run Linux well
enough to finish a Debian install run (!). Actually, it took a while
for it to do so even when the user updated the BIOS from the motherboard
vendor site before attempting to install Debian...
