I've been using POP OS (Ubuntu based distro) successfully for more than a year on the ACER Spin 5 SP513-54N laptop, but now it does not boot any more with pci=nocrs kernel parameter, which is required in order to have touchscreen and touchpad working. But.. it has stopped working now - system does not boot properly and ends on initramfs console.
Upgrade from 21.04 to 21.10 has not resolved the issue. I am attaching the dmesg | grep -iE "warn|err output:
Here is dmesg output without pci=nocrs:

As you may see, there are some lines missing and/or added.
Any help appreciated!
