Works in Thinkpad X1 gen7 Ubuntu 21.04 but laptop freezes after a while

Device is working and I can use the network. But after a while browsing (5-10min) some commands (for example "top") return segmentation fault and shortly after the laptop freezes completely. After reboot everything works again.

Ubuntu 21.04

Interesting. Worried to try this. I just loaded and ran this and it worked under a brief test. I did not test it for 5 minutes though. I am also running Pop!_OS 21.04 so I wonder if that might make any differences. Will test and report back.

Update: Just tested on Pop!_OS 21.04 for about 25 minutes, turned off wifi, wwan only. top/htop working fine after, no segmentation faults or errors. I am using Google Fi (APN: h2g2) and a Google Fi data-only SIM in my X1C7. No errors and pretty good data rates for mobile data! Success on my end but I will use it more over the next while and report back if any errors pop up. Thank you for this driver dev team and contributors <3

I've tested it a bit more and I cannot reproduce the crash. Now running
Linux 5.11.0-31-generic #33-Ubuntu SMP Wed Aug 11 13:19:04 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

So it might have been an independent problem..
Thanks so much for the driver!!
