Hi, I am using guix desktop for day to day usage for many months Everything are working fine till linux-libre <= 5.4.19 But after linux-libre >= 5.4.20 1. No ethernet interface is shown only lo: is shown 2. gdm, Xorg totally stopped working 3. lvm command vgchange -ay taken forever and not able to create device node in /dev/mapper Presently for lvm support, I had added a mapper class with open/close method for many months it is nicely working (It was a work around which work for ~6 volumes at boot time.) I have attached my system config.scm and packages.scm with mail I am not sure if it issue of 1. my configurations (which still work nicely with <= 5.4.19) 2. it is some issue in guix changes 3. or it linux kernel >= 5.4.20 is causing. I had tried searching if somebody had reported it, when I have seen nobody has reported it. Thanks, /sharad
