Description Luya Tshimbalanga 2018-12-13 08:35:02 UTC

I brought a brand new HP Envy x360 laptop and install a distribution. The issue occurred on both with the following error:

The bug still occurs on kernel 4.20.16 notably firmware related. Is it possible for someone from HP addressing the issue as it happened on all HP powered device running on Linux?

Follow-up,
The current ACPI status still remain unresolved to this date. The dmesg is located on https://linux-hardware.org/index.php?probe=ce83006200

Is there someone from HP willing to take a look?

Comment 16 Hans de Goede 2019-11-27 13:37:40 UTC

I've recently hit this seem issue, this is caused by the hp-wmi driver passing a buffer which is not big enough when making WMI related ACPI calls. I've submitted a patch-series which fixes this upstream:

https://lore.kernel.org/patchwork/project/lkml/list/?series=419906

Comment 17 Hans de Goede 2019-12-03 22:27:02 UTC

The fixes for this have landed upstream, closing.

Comment 18 Jeffrey Walton 2020-05-02 04:27:41 UTC

Add a mee too. Hardware is ProLiant DL360 G5. Software is Fedora Server 32 released Apeil 2020. Machine is fully patched.

You are still seeing this with a Fedora 32? This should be fixed at least on HP laptops. I guess we still hve some work to do for the servers.

Can you file a bug against Fedora (bugzilla.redhat.com, component kernel) and attach an acpidump and dmesg output from Fedora 32 there please?

And please provide a link to the filed bug here, then I will take a look as time permits.

Comment 20 Hans de Goede 2020-05-02 12:40:52 UTC

I see that you have already filed:
https://bugzilla.redhat.com/show_bug.cgi?id=1830475

Can you please attach full dmesg output and an acpidump ("sudo acpidump -o acpidump.txt") there ?

Thanks Hans.

Yes, I'll get you the docs on the other issue report.

Sorry to bring this up again. I understand HP does not make it easy on you.

Comment 24 Hans de Goede 2022-06-29 19:29:39 UTC

These errors resurfacing is caused by backporting of some HP-wmi fixes which turn out to cause issues on some models.

The re-introduction of these errors is fixed by:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc6a6ab58379f25bf991d8e4a13b001ed806e881

Please ask the Ubuntu kernel maintainers to backport these too.

Comment 26 Mauricio Faria de Oliveira 2022-08-01 15:29:05 UTC

Hi Jeffrey,

I'm not an Ubuntu kernel maintainer, but work a bit w/ Ubuntu kernel.

Thanks for your report on the ubuntu-devel-discuss@l.u.c mailing list; I came across it, but in the future you can reach the Ubuntu Kernel team at kernel-team@l.u.c (or file a bug on Launchpad in the 'linux' source package).

So, if I understand it correctly (comment 24), the issues were reintroduced by the commits mentioned in the 'Fixes:' tags of the fix commits, i.e.:

Fixes: 4b4967cbd268 ("platform/x86: hp-wmi: Changing bios_args.data to be dynamically allocated")
Fixes: be9d73e64957 ("platform/x86: hp-wmi: Fix 0x05 error code reported by several WMI calls")

However, neither is present in hp-wmi.c for the Ubuntu kernel version reported (5.15.0-39.42), see [1], so the issue might be something else (I couldn't check the remaining of the bug report, sorry).

I know this doesn't help much, but hope it helps a bit. :)
