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,
