XPS 15 9550 wants to update precision 5510 bios?

[Korothi]

i have dell xps 15 9550 using 1.14.0 bios and it just asked me to update precision 5510 to 1.23.0

[hughsie]

@CragW is this the same BIOS?

It seems they've fixed this issue in the metainfo, @Korothi would you want to try again?

[dabrowne]

Can someone please help explain what's gone wrong here? I saw this update in the Ubuntu software updater UI and stupidly clicked install without noticing that it had the incorrect name. Surprisingly, the firmware install completed successfully but my system performance has been miserable since.

I've since reverted back to the most recent BIOS version 1.14.0 for the XPS 9550, however the Intel ME installation failed during the downgrade (I guess it's not possible to downgrade this) so I'm stuck with a potentially incompatible Intel Management Engine package for my system which I suspect is causing my performance issues. Is there any guidance on how this can be resolved?

[hughsie]

@CragW seems like this isn't indeed fixed. Can you investigate please.

[CragW]

Intel ME cannot get downgraded, not fwupd specific problem. @dabrowne would you please raise a ticket to support at dell.com and elaborate the performance issue for further analysis?

@CragW I'm not sure how to go about profiling the performance degradation in a way that would be helpful or meaningful. Do you have any suggestions? All I can say is that since this update my machine has been incredibly sluggish and I'm seeing lagging and sustained high CPU usage for apps which would normally run quite smoothly. Previously running an Ubuntu VM (VirtualBox) was a breeze, now the same VM is basically unusable. I'm noticing similarly degraded performance across all of my commonly used applications (Firefox, Chrome, Slack, VSCode etc).

Can you confirm what has gone wrong for this to happen? Did Dell release an incorrectly tagged firmware update that was picked up automatically by fwupd? I've been a bit busy to deal with it lately, but if you think I'll get some help from dell.com I'll go ahead and open a support ticket, but it would be good if I could go in with a better understanding of how I've ended up in this situation :sweat_smile:

[CragW]

@dabrowne can you pl. send me your service tag for a preliminary look?

Just to confirm, I have the same problem and it doesn't appear to be fixed yet.

This has come back for me too.. This morning I got a notification from the Ubuntu Software app that a "Critical Update" is ready to install:

[CragW]

The update for Precision 5510 1.21.0 should have been removed from the catalog.

[dabrowne]

The update for Precision 5510 1.21.0 should have been removed from the catalog.

Thanks @CragW, this appears to be resolved again - I'm no longer seeing 1.21.0 as an available update.

[davidhall-enactor]

Thanks @CragW the Precision 5510 firmware is not being displayed now. But I'm getting an update notification for a v1.15.0 BIOS which I'm not convinced is correct, as v1.14.0 that I already have is the latest listed on Dell's website for the XPS 15 9550. Can anyone else reproduce this?

Currently I have the same issue, Gnome Software is showing 1.15.0 as available for Dell XPS 9550 which it isn't. Any way to completely disentangle XPS 15 9550 and Precision 5510?

[nahall]

Same here, KDE Plasma Discover is showing an update to the 1.15.0 BIOS for my XPS 9550 but Dell's website shows 1.14.0 as being the latest

It is pulling up the BIOS from the Precision 5510 it seems.

[CragW]

This is what I've heard -> Both BIOS versions (1.14.0 and 1.15.0) are derived from the same source code. Just the update cycles differ due to variations in product lifecycles.

[DPaulW]

The description in fwupdmgr is exactly that for 5510 ( Firmware updates to address the Intel Technical Advisory. Issues: CVE-2020-8758 INTEL-TA-00404) I can't find this being fixed for xps 15 9550 anywhere so please remove this as an option for xps 15 9550 to avoid issues faced by @dabrowne

[MartFab]

Sorry if it is a bit bit tiny of-topic but i just noticed, that my XPS 9550 bios has been updated to 5510 1.23.0 bios. Because I'm a causal user, i haven't notice major drawback for now but what impacts can i expect from it ? And if there is, how can we downgrade as Intel ME doesn't seems to support downgrade ? Thanks!

[davidhall-enactor]

I think the current status of this ticket is;

1. The original issue is that fwupd was showing system updates for the Precision 5510 on the XPS 9550. If a user updated (as @dabrowne did) there may have been a performance impact as a result. This issue is now resolved.

2. However, now fwupd is showing a v1.15.0 system update for the "XPS 15 9550/Precision 5510" on the XPS 9550, which isn't available on Dell's website. I don't know whether there are any known issues updating to this version and am not too keen to find out! @CragW says "Both BIOS versions (1.14.0 and 1.15.0) are derived from the same source code" but I'm not sure this resolves the matter. The question is should fwupd be listing the 1.15.0 system update for the XPS 9550 or not, and I don't think that's been definitively answered.

[DPaulW]

Accurate summary. I would vote :- no, 1.15.0 should definitely not be listed

[vs49688]

I've also just hit this, which raised a red flag because I hadn't seen it on Dell's website.

Any chance we could get some clarification of whether it's safe to upgrade? I'm not game to try it otherwise.

They have set 1.15.0 as a reliable release for Linux.
