Description
The bootloader is stuck on 'loading kernel...' (apparently in stage 2) for about 10 seconds. I am using qemu with kvm enabled, booting via bios.
qemu-system-x86_64 -enable-kvm -drive format=raw,file=os.img -serial stdio
I find this surprising, as on 0.9.23 it was practically instantaneous. Is this expected?

Research direction
Reproduce the delay with the provided qemu-system-x86_64 command and os.img, then compare behavior with version 0.9.23. Trace the bootloader's stage 2 kernel-loading path to identify what accounts for the roughly 10-second pause. Done means the regression is explained and the expected behavior or a verified fix is established.
