As long as the kernel stub does not invoke the SNP protocol itself it is safe for GRUB to assume that it is still in a good state when reaching the Load File2 protocol call.

[Bug 1967562] Re: jammy beta (220330) arm iso pxe boot kernel panic on Ampere Mt. Jade
Well spotted Heinrich. I'd hypothesized that something was shutting down
the network stack, but didn't yet no where to look, and overlooked
grub_net_fini_hw() message! With that hint, I went ahead and tried
commenting out[*] the registration of that callback, and voila, the
ReadFile2 initramfs loading from TFTP worked:
loader/efi/linux.c:348: Providing initrd via LOAD_FILE2_PROTOCOL
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Exiting boot services...
But I'm not sure of the correct way to address it. Perhaps the kernel's
efi stub needs to own network device shutdown to do this properly? I'm
happy to bring this discussion up on the mailing list. But, for jammy,
seems like disabling ReadFile2 initramfs for !riscv64 would be the
safest approach at this point.

I randomly picked another ARM server, a Cavium ThunderX system, and it also fails to net boot w/ jammy's GRUB, but works fine w/ the patch in comment #16. So this is looking like possibly an architecture-wide issue. I tested on an x86 VM, but I didn't see any of the LoadFile2 messages.

GRUB is responsible for loading the initrd into memory, so it is possible that this is a GRUB regression.

When PXE-booted, it was 103244K. 103248K actually matches the initrd size reported by `ls`. I assumed some kind of rounding error, but maybe that 4K difference is a clue. EDIT: No, turns out I was pointing at a daily ISO build and it has been updated, and initrd sizes between the two have a 4K initrd difference. ** Attachment added: "howzit-iso-console.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1967562/+attachment/5578348/+files/howzit-iso-console.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967562 Title: jammy beta (220330) arm iso pxe boot kernel panic on Ampere Mt.

[Bug 1967562] Re: jammy beta (220330) arm iso pxe boot kernel panic on Ampere Mt. Jade
I can reproduce, and I've attached the full console log (!quiet, +debug). Here's some interesting pieces of the log: EFI stub: Booting Linux Kernel... EFI stub: Generating empty DTB error: couldn't send network packet. EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path EFI stub: Exiting boot services... [0.00] Booting Linux on physical CPU 0x12 [0x413fd0c1] [0.00] Linux version 5.15.0-25-generic (buildd@bos02-arm64-058) (gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0, GNU ld (GNU Binutils for Ubuntu) 2.38) #25-Ubuntu SMP Wed Mar 30 15:57:31 UTC 2022 (Ubuntu 5.15.0-25.25-generic 5.15.30) [...] [ 15.338070] Trying to unpack rootfs image as initramfs... [ 15.439137] Initramfs unpacking failed: invalid magic at start of compressed archive [ 15.461425] Freeing initrd memory: 103244K [...] We can see at the end there that the initrd failed to unpack, and that will definitely lead to a "Unable to mount root fs" panic. But why did it fail to unpack? One possibility is that the initrd failed to download. The TFTP server does report that it downloaded: Apr 8 19:38:59 avoton02 in.tftpd[4218]: RRQ from 10.229.58.47 filename /casper/vmlinuz Apr 8 19:39:02 avoton02 in.tftpd[4220]: RRQ from 10.229.58.47 filename /casper/vmlinuz Apr 8 19:39:06 avoton02 in.tftpd[4221]: RRQ from 10.229.58.47 filename /casper/initrd OK, then maybe it only partially downloaded? Well, the amount of memory the kernel reports freeing is close to the size of the initrd, so that's probably not it: $ du -s /srv/tftp/casper/initrd 103248 /srv/tftp/casper/initrd Then perhaps the kernel doesn't support decompressing this compression format. What is the compression format? $ file /srv/tftp/casper/initrd /srv/tftp/casper/initrd: Zstandard compressed data (v0.8+), Dictionary ID: None Does the kernel support that? Let's look at the kernel config: ubuntu@avoton02:/tmp$ dpkg-deb -x linux-modules-5.15.0-25-generic_5.15.0-25.25_arm64.deb x ubuntu@avoton02:/tmp$ grep ZSTD_DECOMPRESS x/boot/config-5.15.0-25-generic CONFIG_ZSTD_DECOMPRESS=y hm.. it does. That's weird. The other mystery is that this all seems to work when booted from the ISO. Let's take a look at that boot log and see if we can spot anything different. ** Attachment added: "howzit-pxe-console.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1967562/+attachment/5578333/+files/howzit-pxe-console.log ** Changed in: subiquity (Ubuntu) Status: Incomplete => Invalid ** Changed in: linux (Ubuntu) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967562 Title: jammy beta (220330) arm iso pxe boot kernel panic on Ampere Mt.
