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

2019-08-09, 14:58 PM

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.

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!

I can confirm this. My E585 now boots as well without the IVRS parameters. Tested with kernels 4.19.67 and 5.2.9 using Arch Linux.

 

Thanks Lenovo for finally fixing the issue!

Yeah! I only have the "psmouse.synaptics_intertouch=1" parameter as requested by dmesg. No more pstate errors, no more clocksource errors... Thanks for fixing it, Lenovo.

Finally :)

Does this mean all suspend issues are fixed aswell ?

I used to disable C6 states with zenstates on boot and wakeup, guess thats the only thing needed now on arch with sway.

@randombot

That was due to the rdrand issue and should have been fixed with systemd.

Does anyone know if the new BIOS resolves the Bluetooth issues?
