Hi,
In cpu-64.cpp, in function Cpu::setup_sysenter, Fiasco try to set IA32_FMASK (called MSR_SFMASK in the code) to ~0ULL. However, only the lower 32bit of FMASK should be written to.
This cause problems on some platforms.
The fix has landed in our public repository [1]. Thank you for reporting this issue.
Regards, Matthias.
