Thanks for quickly responding to the bug.
Our use case is booting real bare metal aarch64 servers from remote iSCSI
volume[1]. Which uses iPXE's iSCSI boot functionality. The booting iPXE script
looks as bellow:
-
:boot_iscsi
imgfree
set username xx
set password xx

PXE booting Focal initrd always gets a timeout, but PXE booting Bionic initrd
works
error: timeout reading `initrd.img-5.4.0-42-generic'.
grub.cfg

grub, kerne
Note that PXE booting Bionic initrd works.
Even though change the initrd compress to gz, it still gets timeout

** Also affects: initramfs-too
I encounter a Synchronous Exception crash when booting shim with
qemu-system-aarch64 on Focal. But on an real aarch64 server this doesn't happen.
Not sure if it is the same issue.

Public bug reported:
iscsi boot fails to boot into rootfs, due to iscsi root disk is not
available in time and mount root fails.
After add 10 secs delay, it can boot into iscsi root disk successfully.
It seems that 'udevadm settle' is not enough to wait for iscsi disk is
available.

Yes, focal initrd is a little larger than bionic one.
