Boot prcess gets sometimes stuck at "TRACE: exiting boot services" when using Uefi and qemu

daniel-keitel commented 1 year ago

When running qemu-system-x86_64 -bios {ovmf_pure_efi_path} -drive format=raw,file={uefi_path} -smp {core_count} the bootloader gets sometimes stuck at:

INFO : UEFI bootloader started
INFO : Using framebuffer at 0xc0000000
INFO : Reading configuration from disk was successful
INFO : Trying to load ramdisk via Disk
INFO : Ramdisk not found.
TRACE: exiting boot services

Higher core counts for the -smp argument result in a higher likelihood of it getting stuck. (I am not sure if it even occurred once at -smp 1)

ovmf-prebuilt = "0.1.0-alpha.1"
occurred independent of used BootloaderConfig
never encountered on hardware
occurred on Linux, Mac and Windows hosts

Thanks for reporting! Not sure what could cause this, but I'll try to reproduce this when I have some time.

I have the same issue, so I don't think it is related to either the kernel or the configuration. Also I tried running this repos tests using smp and got the same error.

I'll spend some time investigating this. This bug is rather annoying when trying to run automated tests.
