Looking at syslog - its clear the memory is being reserved for some reason by the kernel: Memory: 2558908K/16524372K available (16393K kernel code, 4377K rwdata, 10804K rodata, 3224K init, 6580K bss, 13965204K reserved, 0K cma-reserved) Usually the amount reserved is: Sep 22 11:35:57 pdlap01 kernel: [0.099454] Memory: 15926800K/16524372K available (16393K kernel code, 4377K rwdata, 10804K rodata, 3224K init, 6580K bss, 597312K reserved, 0K cma-reserved) Been using linux on this device for years - only noticed since 22.04.1. Both times today when it reserved 13GB - it was connected to the dell dock (dont know if that is relevant yet). No recent changes other than security updates - but I noticed it did this a month or so ago too - but hoped it was a one off.

[Kernel-packages] [Bug 1924624] Re: After upgrade to kernel 5.8.0-49/50 with Intel Gen7 (Haswell/Ivy Bridge/Bay Trail) graphics a lot of glitches render screen unusable
I was using linux-image-5.8.0-55-generic:amd64 - this kernel still has the issues. Reverting to 5.8.0-48 removes the issues. Changing to the 5.4 kernel (latest) also removes the issues -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta-hwe-5.8 in Ubuntu. https://bugs.launchpad.net/bugs/1924624 Title: After upgrade to kernel 5.8.0-49/50 with Intel Gen7 (Haswell/Ivy Bridge/Bay Trail) graphics a lot of glitches render screen unusable Status in linux package in Ubuntu: Fix Released Status in linux-meta-hwe-5.8 package in Ubuntu: Fix Released Bug description: After upgrading to 5.8.0-49, on a laprtop with intel graphics, graphics was suddenly extremely glitchy. Icons from the desktop flash through the browser, windows top bar gets distorted, all sort of glitches appear, parts of characters are missing in terminal, scrolling is inconsistent and the whole desktop becomes unusable. Under wayland the graphics are a bit more stable, but lots of glitches appear anyway, video reproduction in browser is stuttering and wobbly. Booting with previous kernel 5.8.0-48 seems to fix the issues. 5.8.0-50 is broken as well. this is the result of 'sudo lshw -c video' on my hp Elitebook 8470: *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:33 memory:d400-d43f memory:c000-cfff ioport:4000(size=64) memory:c-d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924624/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
