Kernel error & crashes after waking up from suspend & re-loading the driver: shift-out-of-bounds in phydm_phystatus.c. shift exponent 63 is too large for 32-bit type 'int'

[navid-zamani]

Since the last update I got serveral system hangs (display output normal, audio loops, input does not respond), specifically not long after coming back out of suspend. Also, the wifi (via the usb stick using the 8188eu chip) seems very slow, and after the forced shutdown and reboot, is very quick again. And I found this in dmesg, when re-loading the driver (modprobe -r 8188eu; modprobe 8188eu):

I don’t know if the crashes and slowness after wake up and this error message are related, but of course this error is not how things should be, and maybe it solves other things in the process.

It seem that the error message contains everything necessary, but if you need anything more, I’m happy to provide it.

Add this line to sysctl.conf and reboot so it doesn't go into mode suspend: usbcore.autosuspend = -1 Or upgrade your current kernel from the first version 5.15.0 to the current 5.15.51 or later.

Since this is a laptop, not going to suspend is not an option, as the battery would drain too much. I am surprised with how old the kernels in Mint are. So I will go the route of updating to the latest, using Ubuntu Mainline Kernel Installer (since UKUU has committed suicide). Thank you, and sorry for bothering you with an oversight (old kernel) on my part. :)
