Sorry if this is a duplicate post.  I sent an email to devel@edk2.groups.io before creating an account on groups.io. This started with edk2-stable202311.  I bisected this to first bad commit: [e8aa4c6546ad5b04a1100fa2618e424f58e354f5] UefiCpuPkg/ResetVector: Cache Disable should not be set by default in CR0 I tried the lastest ovmf git master with same result.  Reverting the above commit fixed the issue. I am running Arch linux with kernel 6.7.4. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
