With `scsi_mod.use_blk_mq=n` the system resumes fine, so for to me
unknown reasons, that Kconfig option get selected in my Linux kernel
configuration. I remember having similar issues when this was enabled by
default in Linux 4.13-rc?, so it was just a configuration problem and
not a regression. Unfortunately, the Linux configuration files are not
under version control, so I cannot check, but it is probably my fault.

Sorry for the noise, and please tell me, what I can do to get the option
working on this old device.


Kind regards,

Paul
