Hi Greg

no regressions *here* on x86_64 (RKL, Intel 11th Gen. CPU)

Thanks

Tested-by: Ronald Warsow <rwarsow@....de>

====
for the record:
today I had a crash with 6.9.4, see below
seems not to be reproduceable with 6.9.5-rc1

Kernel was compiled with LLVM=1 and Xe Graphic driver
Crash happend 3 times while editing a LibreOffice Calc sheet
only a hard reset got the box to live again
