Date: Mon, 11 Apr 2022 12:38:57 UTC
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263219
Bug ID: 263219
Summary: Kernel Panics when doing IO on USB3 device
Product: Base System
Version: 12.3-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: bugs@FreeBSD.org
Reporter: luciano@vespaperitivo.it
When writing to a hard disc accessed via USB3 I get a panic and a kernel
coredump. I've recompiled my GENERIC Kernel with debug; uname -a says
FreeBSD mordax 12.3-RELEASE-p5 FreeBSD 12.3-RELEASE-p5 GENERIC amd64
