I saw "ref tag" errors on NVMe devices, starting with 4.18 kernels. The
fix was:

Running a heavy I/O load on multipath/dual-ported SSD disks attached to
a SAS3008 adapter (mpt3sas driver), we are seeing I/Os get aborted and
tasks stuck in blk_complete_request() and this sometimes results in
hitting a BUG_ON in blk_start_request(). It would appear that we are
seeing two comp
t NULL before doing cleanup on it. Since in the
error case this is also not NULL, it ends up trying to access an invalid
task pointer.
Solution is to assign NULL to ha->dpc_thread in the error path to avoid
kthread cleanup in that case.

Hi all,
I am seeing an issue while using an LSI-3008-based adapter (mpt3sas
driver) on a PowerPC system (although I am not yet convinced it is
architecture dependent). When I create a RAID1 volume, the physical disk
devices get "hidden" as expected however the various kernel objects are
