https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241718 Bug ID: 241718 Summary: rack_tcp: page fault/kernel panic in rack_output when installing Vivaldi browser via wine Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: kumba@gentoo.org Running 12.1-RC2 on an Intel NUC8i5BEH with a custom kernel config, and usi= ng the TCP RACK stack (from Netflix), I was attempting to install the Vivaldi = web browser (Chrome clone) as a standard user via i386-wine-devel in an Enlightenment instance. At some point in Vivaldi's install, it must be mak= ing a callout back home (telemetry/stats logging??), and when it does this, the= re is a page fault, the kernel panics, and the system immediately reboots. Th= is issue is also reproducible using 64-bit wine and Vivaldi's 64-bit installer. Partial log is below, manually transcribed from an image I took of the scre= en.=20 I didn't get all of the "WARNING" lines due to not having much time to get a picture. I set dumpon to compress the dump, and this is what bought me a f= ew extra seconds. However, savecore reports on reboot that no dump was saved = (I think). And although the drm-kmod drivers below do not appear to be a factor, I wan= t to note that I am using rebuilt drm-fbsd12.0-kmod from ports in package format= , in an attempt to get a working X11 up on this NUC device. In case there is any curiosity about the "WARNING" lines.
