[Kernel-packages] [Bug 1896482] Re: acpi event detection crashes
I have had this same issue for at least a year. It's still an issue with kernel 5.11.0. The following lines in the stack trace looks almost identical: [292156.350702] ACPI: EC: interrupt blocked [292180.635315] [ cut here ] [292180.635318] WARNING: CPU: 1 PID: 297907 at kernel/workqueue.c:1419 __queue_work+0x2ce/0x340 [292180.635429] CPU: 1 PID: 297907 Comm: kworker/1:1 Tainted: P O 5.11.0-17- generic #18-Ubuntu ...

[Fix] Upstream commit 03e9a0e05739cf reworks ec_install_handlers to avoid initialisation failures. The other three patches are prerequisite to apply 03e9a0e05739cf on focal kernel. [Test] Tested with Lenovo ThinkPad X1 Carbon Gen 8 [Regression Potential] Low. The patches were cherry-picked from mainline kernel (two since 5.5 and two since 5.7) = Original Bug Report = Right after booting, acpi lid open/close is detected as it should be by the kernel, but some time later it crashes, so I have to manually suspend the system.

[Kernel-packages] [Bug 1859754] Re: add ucm to make alsa/sof driver work under PA (variants of Lenovo X1 Carbon 7th, Dell cnl and cml machines)
Hello. I am wondering why this only applies to certain models of the X1C7. I had to make an additional file to get my Mic working: LENOVO-20QDCTO1WW-ThinkPadX1Carbon7th-20QDCTO1WW.conf Is this something I should report upstream? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to alsa-lib in Ubuntu. https://bugs.launchpad.net/bugs/1859754 Title: add ucm to make alsa/sof driver work under PA (variants of Lenovo X1 Carbon 7th, Dell cnl and cml machines) Status in HWE Next: New Status in alsa-lib package in Ubuntu: Fix Committed Status in alsa-lib source package in Bionic: Fix Committed Status in alsa-lib source package in Eoan: Fix Committed Bug description: This ucm is only for Eoan and Bionic, for focal and future versions, we plan to integrate the ucm2 instead of this ucm, and the ucm2 depends on the alsa-lib-1.2.1 and pluseaudio-v14, the ucm2 is under developing by the community, is not ready yet. [Impact] In the oem project, we have a couple of Lenovo and Dell machines which connect the digital mic to PCH directly, this design needs the new sound driver soc/sof, and this driver can't work under pulseaudio automatically, we need to integrate the ucm for the driver, then the sof dirver could work under pulseaudio and gnome. This ucm is maintained by intel audio team, and it is not upstreamed and will not be upstreamed, since the community is developing the ucm2 which is based on at least alsa-lib-1.2.1 and pulseaudio-v14.0 (still under developing), for bionic and eoan, we have to integrate this ucm since the alsa-lib version is too low. For focal and future version, we are going to integrate the ucm2 after the ucm2 is ready. This ucm is already verified in the oem project, now it is time to put it into the stock ubuntu. [Fix] These ucm files are backported from sof_ucm1 branch of https://github.com/thesofproject/alsa-ucm-conf.git [Test Case] Boot the eoan kernel or oem-osp1-bionic kernel, then check the log of pulseaudio, the ucm files are loaded successfully, then check the gnome-sound-setting, both output and input devices work well. [Regression Risk] Low, just add some new ucm files, and this will not affect other machines, and those new added ucm files are only used by specific machines which enable the sof driver.
