There are two major regressions noticed on linux next tag 20201008.
I will bisect this problem and get back to you.
1) qemu_i386 and qemu_x86 boot failed due to mount rootfs failing [1].

steps to reproduce:
--------------------------
1) qemu boot command:
/usr/bin/qemu-system-x86_64 -cpu host -enable-kvm -nographic -net
nic,model=virtio,macaddr=DE:AD:BE:EF:66:06 -net tap -m 1024 -monitor
none -kernel bzImage --append "root=/dev/sda rootwait
console=ttyS0,115200" -hda
rpb-console-image-lkft-intel-corei7-64-20200723162342-41.rootfs.ext4
-m 4096 -smp 4 -nographic
2) boot x86_64 with linux next 20201008 tag kernel and attach SDD drive.
mkfs -t ext4 /dev/<drive-partition>
