Hi , We are noticing the below warning in the latest 5.4.252 kernel bootup logs. WARNING: CPU: 0 PID: 0 at arch/x86/kernel/fpu/xstate.c:878 get_xsave_addr+0x83/0x90 and relevant call trace in the logs , after updating to kernel 5.4.252. I see that issue is due to this commit https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.4.252&id=6e60443668978131a442df485db3deccb31d5651 This is seen in the qemu instance which is emulating the host cpu and was deployed on Intel(R) Xeon(R) Gold 5218 processor. I revert the commit and there is no WARNING and call trace in the logs , Is this issue already reported and a fix is available? Could you please provide your inputs. Regards, Rajesh.
