https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230962 Bug ID: 230962 Summary: Kernel panic when writing extended attributes with soft updates enabled Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: 2t8mr7kx9f@protonmail.com Created attachment 196617 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D196617&action= =3Dedit A screenshot of the panic message. This is a continuation of the following bugreport: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230732 I did some digging to try and get to the root cause. It appears that it has nothing to do with GELI, I can also reproduce this on a plain UFS volume. T= he culprit seem to be extended attributes. Freebsd panics reproducible with=20 "panic: softdep_deallocate_dependencies: dangling deps"=20 when using rsync with the -X option ("preserve extended attributes") to a volume with soft updates enabled. This appears to be some kind of race condition - transferring the files one-by-one works, the panic occurs only when transferring the whole directo= ry. Turning off soft updates (-n disable) or using rsync without -X prevents the panic from occurring. The exact same command worked with 11.1-RELEASE. The attached screenshot shows the panic message. Please let me know if I ca= n be of further assistance! --=20 You are receiving this mail because: You are the assignee for the bug.=
