This bug is awaiting verification that the linux-raspi/5.11.0-1028.31 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed-hirsute'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

In the image from cdimage (2021-06-30), I see: [ 1.856540] random: crng init done [ 1.871798] loop: module loaded (see https://paste.ubuntu.com/p/CkfWXY5Vgf/) while if I build an image from latest snaps in the 20/stable channel, I get: [ 1.855481] random: crng init done [ 5.349491] loop: module loaded (see https://paste.ubuntu.com/p/CNt42gdDcZ/) The pi-kernel snap revision is 353. [ Test Case ] $ sudo dmesg | grep -B1 -A1 'loop: module' [ 0.791122] cacheinfo: Unable to detect cache hierarchy for CPU 0 [ 4.903386] loop: module loaded [ 4.906092] spi-bcm2835 fe204000.spi: could not get clk: -517 [ Fix ] Set CONFIG_BLK_DEV_LOOP_MIN_COUNT to the default value (8). [ Where Problems Could Occur ] Loop devices need to be created on-demand if more than 8 are required. If that fails, user space will fail.
