Subject: [PATCH 0/1] Write commands abort hang
Date: Fri, 17 Jul 2026 16:38:27 +0200 [thread overview]
Message-ID: <20260717143828.76291-1-mlombard@redhat.com> (raw)
One of our customers reported that sometimes the LIO driver hangs when
performing a LUN reset while I/O is underway.
I was able to reproduce the hang by using the following libiscsi patch:
https://arkamax.eu/misc/dataout_abort_libiscsi.patch
INFO: task kworker/5:0:514619 blocked for more than 46 seconds.
