[Bug 1956964] Re: iwlwifi connection drops using AX200
I can confirm getting same errors on an LG gram laptop, running Intel AX201 wifi hardware. I get frequent disconnect and reconnects until finally, it failed to reconnect, despite reboots. I also see the message concerning a microcode software error. Removing ucode newer than v55, as suggested by Olszewski failed to recover wifi operation. Upon boot, I note in the log that indeed v55 is loaded, followed by a large dump (too large to type in full here because I cannot connect to the disabled machine.)

[Bug 1945289] Re: Failed to properly resume from S3 (suspend-to-ram) on kernel version 5.13.0-16 (installed while updating to impish), amdgpu driver.
Experiencing the same problem after upgrade to Impish. I have determined that the desktop does actually start after a resume from suspend, but the screen remains blank, with the backlight on. (To determine this, I used a keyboard shortcut to launch a terminal window and typed a reboot command successfully.) Everything in the kernel log seemed normal for the interval around the suspend/restore (although there's so much stuff there, it's hard to be sure.) The screen does come on OK after a full reboot. As with the OP, suspend/restore is OK if I back off to using the 5.11 kernel. Also as for the OP, my system is using the amdgpu driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945289 Title: Failed to properly resume from S3 (suspend-to-ram) on kernel version 5.13.0-16 (installed while updating to impish), amdgpu driver.

I tried returning to 10.10 after the kill switch proved permanent in 11.4. It was still stuck. Re-installing 11.4 from scratch didn't help. Could it be that something is set in the BIOS? Or could it be in my home partition (which was carried over).

[Bug 481680] Re: After upgrade to Karmic, _alsactl kernel process segfault on boot -- no sound
Some additional information.
Running sudo alsactl init yielded syntax errors in the file
/usr/share/alsa/init/default. At several lines in the file, the braces were
mismatched: Eg,
ENV{has_pmaster_vol}==true,CTL{values)=100%,GOTO=headphone0_end
I fixed those errors, after which alsactl init produced the following
errors:
