Everything works great on my new P1 Gen5 with the noteable exception of an irritating network and/or USB issue. Laptop doesn't have a built in ethernet port, so I'm using a Caldigit3 as a dock, which ... generally... works fine except for sporadic problems. There are two that I've been able to hone in on and would appreciate anything I can do to troubleshoot further. I'm not an Arch expert, but have been enjoying it thus far as my daily driver.
Issue #1: The wired NIC in the Caldigit seems to randomly stop working until I restart systemd-networkd. I know this because the Wifi card turns on and I'm on the edge of signal, so everything goes to crap until I disable wifi & restart networkd. I have similar issues with other Thunderbolt/USBc. Nothing of relevance in system log that I can see other than wifi connection attempts.
Issue #2: The entire connection to the Caldigit seems to drop with the exception of the display (DisplayPort monitor, works great). Keyboard, NIC, all other USB devices stop working and don't reconnect until I reboot.
Things I have tried:
- I've looked extensively through the system log using dmesg and cannot for the life of me find anything related either before, or after the occurance of the issue.
- Re issue #2, I've tried restarting systemd-udev and bolt services to no effect.
- echo 1 > /sys/bus/pci/rescan after the issue occurs. Nothing.
I know there are things I've tried that I'm not recalling at the moment, but would gladly take any assistance to help me pin down the problem. At this point, all signs *seem* to be pointing to thunderbolt/usb, but I'm not sure. I have had Issue #1 when using a different USB NIC also.
Currently running 6.1.12.
Thank you for any assistance.

Found a solution, and posting in case it helps someone. I could repro the issue by disconnecting and reconnecting the dock. Disconnect was fine, reconnect turned the display back on, but keyboard/nic dead. Also odd problems with the NIC per above.
The problem ended up being a udev rule, per this issue: https://bbs.archlinux.org/viewtopic.php?id=261153.
I removed this file and rebooted.
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="05c6", ATTR{idProduct}=="9205", ATTR{power/autosuspend}="-1"So far thing seem stable and I can disconnect/reconnect the dock now without loosing keyboard/nic.
