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

Well to be fair the XPS 15 is in another price bracket.

 

Also, I do not think the problems with Linux are entirely Lenovo's responsibility. I mean yes the BIOS has a bug and the GRUB needs to be manually edited to "patch it" but our machines have working without problem since we did that *and* moved to Ubuntu Mate 19.04. No more freezes or sleep of death.

 

This means that something else was fixed on the OS side (probably about AMD Ryzen's support).

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

Just tried the latest Arch Linux Kernel 5.2.5.arch1-1. At least in my setup the additional IVRS parameter is still required.

 

I really hope they fix this issue soon. Only Linux enthusiasts will be able to add this parameter (or even be capable of finding out that it is required int the first place). Someone just giving a live ISO/USB image a try will expect it to work out-of-the-box without any tinkering.

Someone Succeded Installing FreeBSD? I cannot find a way to set IVRS parameters at FreeBSD.

and is it true that Lenovo is going to fix BIOS at Late August?

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

Using the latest BIOS, Ubuntu19.04, I only need ivrs_ioapic[32]=00:14.0 to install os, and there is no other severe bugs. And in order to deal with error in logs, I add pcie_aspm=off, but I don't know if it's right.

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

To boot FreeBSD, wait until you see the logo and press 3 for boot options, once there type:

 

set hw.pci.mcfg=0
boot

You also have to  add it to /boot/loader.conf, more info can be found on the mailling list:

http://freebsd.1045724.x6.nabble.com/acpi-issues-on-FreeBSD-current-r350103-on-Thinkpad-A485-tt63399...

 

In the freebsd-current this issue is fixed, but with the releases you still need to set this.

The reason I'm not using it is because I swapped my wifi card with a intel 9260, which is not yet supported by FreeBSD. Maybe you have better luck with the default wifi card, good luck Smiley Happy

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

Just to advise, got Mint 19.2 installed with the usual ivrs 32,33 and iommu=pt stuff, from a DVD image (use the 'compatibility' choice to run the DVD) to an internal HDD. Edit /etc/grub/default and run update-grub before booting the HDD. Did system updates which included some amd firmware then rebooted again just to make sure it didn't keel over. Haven't looked at it in any detail but it seemed to be stable for a couple of hours.

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

iam using Ubuntu Mate 18.04.

since today morning after booting the OS iam not able to connect to wifi.

its running fine in windows 10. (me using dual boot)

 

i have to reinstall the wifi drivers. and let u know. 

 

i was thinking to shift for 19.04 or 19.10 , but reluctant, as the post configuration of my packages will take more than half a day of time.

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

I was running Pop_OS and had the same issue, tried a few other Ubuntu based distros (Ubuntu, lubuntu, xubuntu) and none of them resolved my WiFi issue. Works in live cd, stopped working after install. This happened after the last firmware update, which by that point I was too fed up to try to rollback the update so I am selling my e585. I am so incredibly unhappy with this laptop.

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

Hurray! A fix from Lenovo!

 

Bios version 1.54 has just been released and from the Readme I quote the following:

 

[Problem fixes]
- Sync IOAPICID in IVRS and APIC ACPI tables (Linux).   
- Enhance to address vulnerability security issue

 My E585 now boots OpenSuse with the IOMMU-related flags erased.

 

Thanks Lenovo!
