[Bug 887793] Re: [HP 6710b] Kworker constantly taking about 100% CPU

Tried to read all.. but I think I have different info.
I originally got the 100%CPU on kube and ended up disabling and not starting any of that, but the 100% CPU started on another process.. just one, so removed and rebooted.. and again it's not on gnome-shell.. however found the cpulimit and set gnome-shell to 30 or 40%. It functions now if I don't open too many windows. (or open a browser with too many by mistake and manage to get ctrl-alt F2 fast enough to log in and kill it, which usually unfreezes X. I did buy a 1300Mb wifi a while back, and no support for linux, so I dug up the firmware (dual channel, so 2) and added.. seemed ok for weeks, but that's when KUBE stuff started chowing down on my CPU.
I'm not good/familiar with this whole bug thing and my time is super valuable right now, so Please just say if I do something wrong or need to add info.
Also, some mention 20.04, but I've been on 18.04 LTS over 6 months now.
Plus some issues with the firmwares, I have multiple RTL chips. from, prolly 14 years ago now, to the two new ones in the dual band ethernet card. One other I'm pretty sure is in unused 2 SATA RAID onboard (14 yr old)
Dunno, happy to provide more info but my time is worth to much right now to not clean install in a couple days if it's not fixed. I can't work with 6 windows.. often over 130 win/tabs and close to 200 on Win 7.1.. but then it gets slow and warning, now.. an extra window and I better get to ctrl-alt-F2 quick or hard boot.
Let me know. I hope it tells me if there's replies.. (will look a bit)

might try pull the wifi.. but wanted to do some stuff.. but have much
more critical todo anyway.

Cheers - Andrew
