Well, previously on mint as well as the Ubuntu liveimage, fans would run at medium to high speed constantly despite running in gpu rendering mode and no visible cpu strain. The air coming out of the vents would be cold as well. When i booted 5.6.0, the fans ran fast for a minute or so after boot, then everything returned to normal. Like I said, it would merit a separate report. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1886341 Title: Kernel Regression between 5.4.0-26 and 5.4.0-40 causes laptop internal audio devices to fail to load w/o unacceptable workaround (Lenovo IdeaPad 5 15IIL05) Status in linux package in Ubuntu: Confirmed Bug description: On Ubuntu 20.04, running kernel 5.4.0-40-generic, the internal speakers, headphone jack, and mic do not work at all.

[Kernel-packages] [Bug 1827822] Re: kernel null pointer dereference
No I can not reproduce this. Which is not that surprising, deep kernel bugs are unlikely to be correlated with anything the user is doing at the UI level. System is still crashing sporadically, they do not occur on any of my other systems, nor did they happen on this system before a certain date, which inclines me to claim that they were not happening with older kernels. It did lock up again this morning. Unfortunately the last 5 minutes of the syslog file were corrupted and contained no useful information, so I could not tell you if it was the same problem or not. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1827822 Title: kernel null pointer dereference Status in linux package in Ubuntu: Incomplete Bug description: System started freezing up a couple days ago.
