https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D267187 Bug ID: 267187 Summary: System freeze on a T490 laptop Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: henrix@camandro.org Some time ago I tried to migrate my laptop to FreeBSD. I've managed to inst= all 13.0 and everything seemed to be fine, but then I started having these comp= lete system freezes. Since I was running X, I wasn't seeing anything on the cons= ole. I didn't had too much time to investigate (and learn!), so I had to abort t= he migration. Today I tried to repeat the experiment with 13.1, on a Lenovo 13.1. The sys= tem freeze happened again while doing the installation: * I was configuring networking * iwm(4) scan didn't returned any wireless networks * plugged an ethernet cable to try to use the em(4) driver... * the system stopped responding, the laptop started to get hotter and the f= ans started I had to hard-reboot, of course. My question: I do I debug this? If I had to guess, it it's a network driver bug, either iwm(4) or em(4), but how can I get more info when this happens?= I plan to try to re-install again without using the iwm(4) driver. Another detail (probably irrelevant): I'm installing with encrypted root-on-zfs. --=20 You are receiving this mail because: You are the assignee for the bug.=
