Hi, I'm running OpenBSD-current (OpenBSD 7.3-current (GENERIC.MP) #1314: Tue Jul 25 17:02:17 MDT 202) for many years now on my Lenovo Thinkpad T14 AMD Gen1 without any big issues so far. Few weeks ago, my system started to hang randomly, but many times, it was linked to Firefox high memory usage or after a suspend. In both case, the network is unreachable and the only way to "fix" this issue is to do an hard reboot.
In fact, I got many X11 hangs in the past, but those were easily fixed by killing X11, firefox or just by remotely rebooting the laptop. Here my dmesg: https://dmesgd.nycbug.org/index.cgi?do=view&id=7234
