Is this a bug related to AMD (CPU) or XFS?

Hard to know without seeing the rest of the stack trace, is this all you got?
Yes, that was the only entry in the log file, I could not wake up the
monitor to get any more information.


You hit an assertion failure in xfs.

Are you running with CONFIG_XFS_DEBUG?
Nope.

CONFIG_XFS_FS=y
# CONFIG_XFS_QUOTA is not set
# CONFIG_XFS_POSIX_ACL is not set
# CONFIG_XFS_RT is not set
# CONFIG_XFS_DEBUG is not set
