Systems that support LBR formats that include TSX information but do
not support TSX require special handling when saving and restoring MSR
values. For example, see the Linux kernel quirks[1, 2] in the MSR
context switching code. As a wrmsr with certain values under these

... as it is very helpful to diagnose VM entry failures due to MSR
loading.
