No, not really sure why he's talking about but on Arch/Manjaro I've always had to use the ioapic parameter to get it working

As of 1/11/19 in post number 66 , I no longer needed the IVRS override.  I still don't.  There's an image of my boot command line in that post.

Re: ThinkPad E485/E585 - Firmware bug ACPI IVRS table

I am facing the Screen blinking (every 5 seconds) while using the eclipse tool , 

I am using Ubunut Mate 18.04 LTS in my Thinkpad E485 . 

I guess its due to improper graphics support in mate Os. 

 

does anybody know if they are facing screen blink in ubunut 19.04 (or any other flavors you are currently using).

There is no blinking in Ubuntu Mate 19.04. No other bug has been reported yet. We do not use Eclipse though.

We have been told that a new BIOS with the IVRS patch will be released near the end of August.

"We have been told that a new BIOS with the IVRS patch will be released near the end of August."

 

Is there an offical statement of that somewhere? I've been searching for one  and cant find anything

Re: ThinkPad E485/E585 - Firmware bug ACPI IVRS table

Wow what a ride i've had in the past few days.

 

POP_OS had an unrelated issue to all of this that I couldn't resolve so I erased and installed. I decided I might as well distro hop since apparently you don't need to extra entry for ivrs table in Arch, so I download new firmware update that they recently released and then I downloaded arch and....well idk dude but that didn't work for me, I still had to use the extra line. I was having some issues with that so I got impatient, and decided to go back to pop_os (if this laptop didn't already have so many issues, i'd deal with the extra work it normally takes to install arch, i've installed it on a VM before so I get it)

 

well, I loaded Pop os 19 and after an apt update command with a reboot my wifi no longer worked. I decided it was likely something that got updated so instead of investigating I decided to install 18.10 LTS instead. Again, worked in the live usb but after reboot where the setup guide tries to get you to log into various services COULD NOT find any wifi networks. I rebooted into windows 10 (I have a separate drive for windows) and wifi works fine.

I'm so tired of this laptop. I regret doing the firmware update because until then I was "dealing" with the ivrs thing, I memorized the command and got real good at knowing when to check for pop_os overwriting the command. I really want to sell this thing and buy something else. Something with intel I guess since this seems to be related to AMD based on other postings. I can't believe out of all the thinkpad laptops I picked up, I picked the ONE that has terrible linux compatibility.

Anyway, does anyone know how to roll back to the march firmware update? I can't find it on the website. If I have to use windows then this laptop is useless to me, and I don't want to VM linux.

It's been said in this topic that you can downgrade, so download an older bios version and install it.
