description |
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. |
[ 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. |
