You have filed the bug against the linux kernel package, but from what I can tell, this does not necessarily look like a kernel issue. This could rather be an issue with the installer maybe? The way the swap partition is set up during installation seems to be the problem.

During installation I choose Manual configuration, I select a partition for / and I select a (swap) partition for use as swap. During the use of Kubuntu, especially with multiple users that use multiple tabs in Chrome, the laptop becomes suddenly very slow, in fact unusable. Only powering it off and on helps, but after a while the problem occurs again. A look in Partition Manager learns swap is not enabled, even though I explicitly selected this during installation. I can turn on swap in Partition Mgr, but after the next boot it is disabled again. I can only make swap permanent by manually editing /etc/fstab. The same problem occurs on my other machine, swap is not enabled after boot. Here is the contents of /etc/fstab of that machine (i.e. not yet edited manually): # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a device; this may # be used with UUID= as a more robust way to name devices that works even if # disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> UUID=490C-4D3C /boot/efi vfat defaults 0 2 UUID=099c2edf-527f-4242-8c29-5e8fc0ba2786 / ext4 defaults 0 1 /swapfile swap swap defaults 0 0 tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0 Note: we do see a /swapfile here, but swap is not enabled after reboot. Only after changing this to something below it becomes permanent enabled.
