** Description changed: + [ Impact ] + I am seeing what looks as a regression in pi-kernel snap for UC20: there are around 3.5 additional seconds spent in boot time. 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.
