Hello again, the gods must definitely hate me. Your testing kernel got replaced immediately. Automatically. I do not understand it. I have never used any automatic updater and I always do all updates by hand. Anyway, the original kernel had been back with next reboot. OK, no problem I told to

Joseph, I have installed the patched kernel. As of now, I have a USB hub connected with four drives attached to it. It is twice as much as I could connect before. The syslog seems to be perfectly clear and kswapd does not hang with 100% CPU consumption. I am stressing the drives a bit and

Thank you again. I have to say that I am not experienced in the standard Ubuntu or kernel update processes thus I was unsure how to interpret Joseph's message. I also do not want to waste your time but may I ask if you can tell me where I can check or what/where I can search for? Thank you in

Amazing, thank you very much. I do not know about any workaround. Plugging the third HDD into another USB port brings the same result. On the other hand, it is possible to use USB flash drives. Probably because they are not UAS devices. I had been running a three USB HDDs setup to the day the
