Failed to resume from S3 if in battery mode

[acelan]

It stuck while resuming from S3 without AC. https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1883336

Sku: Dell Precision 7730 BIOS: 1.12.1 (11/11/2019) Kernel: Ubuntu 4.15.0-1081-oem & mainline 5.7.0

1. Boot up the system(with AC or Bat only)
2. enter S3, unplug AC if plugged, can't wake up the system
3. enter S3, plug AC, the system can be waken up by power button

Can't reproduce this issue with the intel-microcode=3.20180312.0~ubuntu18.04.1 in bionic repo. After upgrade this package to intel-microcode=3.20200609.0ubuntu0.18.04.1 or the previous version leads to the resume hang issue.

Acelan, just to confirm, this failure to resume occurs with both the 0x00ca from the 20191115 release as well as the 0x00d6 version from the 20200609 release, correct?

Thanks.

[zfil]

I've a similar configuration and the problem occurs with 20191115 and 20200609. With 20191115 the problem is even worse: I can't boot in battery mode it hangs at "loading initial ramdisk"

[acelan]

@stevebeattie, right, this issue could be reproduced on both version of microcode.

[mbidewell]

I have a Dell Precision 7530 and have hit this issue as well. For me, firmware 20191115 works but 20200609 does not.

[bionade24]

I have a Dell Precision 7540 with an i9-9980HK and only have the problem, that I can't boot without AC plugged in. @zfil Have you already opened another issue for that?

[new0ne]

I am facing the exact same issues on the same machine: Precision 7540 also with a i9-9980HK:

• Wont boot without power supply (removing the ucode update from grub is considered as "dirty workaround" when i desperately need to boot my system without ac attached)
• Wont resume without power supply, if its suspended for more then x minutes

[bionade24]

As it only affects Dell we should all complain at the Dell support and link this bug that they'll fix it soon, especially if you paid for the support.

[hmh]

The standard vendor fix will be to update the firmware, in which case the OS stops updating the microcode, and the bug is not triggered.

The underlying issue is not going to be addressed by Dell, regardless of where it lies (Dell firmware, Intel microcode, Linux S3 resume path or SMP/AP bringup).

I've had this issue as well on my dell precision 7530. Interestingly, neither of my coworkers who also have the same model with identical specs ever had issues with this so whatever the issue is, it might be related to some bad hardware batch or something like that.

Initially when I was running ubuntu 18.04 I had intel-microcode 3.20200609.0ubuntu0.18.04.1 and could never resume from suspend on battery. I followed the answer here to fix it by installing intel-microcode=3.20180312.0~ubuntu18.04.1 instead and this fixed things.

After upgrading to ubuntu 18.04 I could not install that version any more, the only versions I see are 3.20200609.0ubuntu0.20.04.2, and 3.20191115.1ubuntu3 The latest version of these broke sleep (again), so I installed 3.20191115.1ubuntu3 from the 20.04 packages and this worked fine.

I'll be bugging Dell support about this because I'd really like this to get fixed before the next LTS release. Let me know if there's anything I can test.

06-8e-0a microcode has been updated to revision 0xe0 in microcode-20201110 release, does the newer microcode revision help?

[tschwinge]

As I report on https://www.dell.com/community/Precision-Mobile-Workstations/Precision-7540-will-only-boot-Linux-if-charger-is-connected/m-p/7739866/highlight/true#M4605 regarding my Dell Precision 7530:

It seems as with the most recent BIOS Revision 1.14.4 (13 Nov 2020) in combination with most recent intel-microcode package version 3.20201110.0ubuntu0.18.04.2, the issue is resolved: system boots fine, no workarounds or package downgrades necessary anymore. :-)

Usage of the latest firmware revision may render OS microcode package version irrelevant, as the former may contain the latest microcode revision available, thus eliminating the need of OS-driven microcode update (that may be the culprit of the initial report).
