** Bug watch added: Linux Kernel Bug Tracker #216322 https://bugzilla.kernel.org/show_bug.cgi?id=216322 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-oem-5.17 in Ubuntu. https://bugs.launchpad.net/bugs/1983177 Title: suspend fails with "freezing of tasks failed" messages Status in linux-signed-oem-5.17 package in Ubuntu: Confirmed Bug description: Trying to suspend a first time, the system came back on. A second attempt turned the screen black but the system still would not suspend. With intervals of about 20 seconds, I received messages on screen like the following one: "Freezing of tasks failed after 20.008 seconds (1 tasks refusing to freeze, wq_busy=0)". See the appended snippet from journalctl for details. When I touched the keyboard after the third such message, the system locked up and I had to shut the system down by pressing the power button. I am now on linux-image-5.17.0-1014-oem. I upgraded from linux- image-5.17.0-1013-oem because that one caused random system locking.
