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

It's basically impossible to do any proper on this laptop. Whenever you need the CPU and it starts maxing out, you've got about 5min before it crashes.

 

The Macbook is too underpowered so I found a refurb XPS 15 with better specs than this (and similar price!). Installed Manjaro with no issues and it's been running a dream. Time to pawn this Lenovo off... Such a shame.

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

Why was this thread moved to "Other Linux Discussions"? Lenovo did not even bother to comment on it. It is not a Linux issue. Not being able to boot Linux is a symptom, the problem is buggy Lenovo firmware.

 

Let's face it, the E485 and E585 "ThinkPads" will remain beta (alpha?) quality devices with known, but unfixed issues (that were fixed in the A485 and A585 monts ago!). I guess we can be happy that keystrokes are now being processed in the correct order most of the time... For me, unfortunately, the bottom line is to stay away from "ThinkPads" in the future.

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

I was able to install Ubuntu 18.04 but now sometimes get CPU freezes. I know that disable C6 reduce these freezes but I was not able get this working in Ubuntu:

Will try with Debian since I was be able to get that scrip working in a server with 2700X.

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

For what it is worth I've had some luck with ubuntu 19.04. I've been using the system with 19.04 for more than a week and I haven't experienced any hangs which I had regulary with 18.04. I've also disabled Bluetooth in the BIOS and I am using a USB bluetooth adapter. Note that I was also doing this with 18.04 but still had system lockups every couple of days.

 

I'm using:

GRUB_CMDLINE_LINUX="ivrs_ioapic[32]=00:14.0 ivrs_ioapic=00:00.1"

 

Let us know your experience with Debian. I'd be interested to hear as I was thinking of trying Debian on my E585.

 

P.S. I haven't had any wake from sleep issues with 19.04 yet. With 18.04 waking from sleep I would end with a black screen ~20% of the time.

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

I'm currently running Zorin OS 15.  It's on kernel 4.18, and is based on Ubuntu 18.04.

 

With the 'ivrs_ioapic[32]=00:14.0 ivrs_ioapic=00:00.1' parameters I've yet to have any issues with waking.   It has been about 3 days of moderate use without issue so far.  FIngers crossed.

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

Do you see something at all?

 

I had an issue, but with other computers, where it would boot instead to the EFI shell. If that's your case you need to, using it, select boot device File and navigate to the Linux one (sorry, not easy to describe in text form)

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

I have a 500G hdd and and 100G ssd. 

I had to wipe out the Window10 from the laptop to confirm if the  Linux grub menu is loading.

i followed the suggestion via https://medium.com/@jthegedus/ubuntu-19-04-lts-on-lenovo-thinkpad-e485-bf2d6cfd9cad

 

even after wiping out the windows and installing ubuntu 18 or 19 , grub menu does not showing at all.

 

Later i installed windows in 500G partition and then again i successfully installed ubuntu 19.04 in 100G ssd. 

selected 100g to be first boot device , but no use windows loads directly, then

selected 500G to be first boot priority, again the windows loads. 

 

iam i doing any thing wrong.
