This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The calibration code issues raw HID feature report for reportID 0x02. When Steam is running, it issues a feature report for reportID 0x12 typically just prior to hid-sony requesting feature reportID 0x02. The result is that 'ds4_get_calibration_data' receives the data Steam requested as that's the HID report returing first. Currently this results in it processing invalid data, which ultimately results in a divide by zero upon a future 'dualshock4_parse_report'. The solution for now is to check within 'ds4_get_calibration_data' to check if we received data for the feature report we issued and if not retry. Please consider to add this patch to Ubuntu LTS kernels.

[Kernel-packages] [Bug 1935846] Re: Sony Dualshock 4 usb dongle crashes the whole system
I would have thought that this patch upstream would have been suitable for stable series. It seems like the bug that the patch fixes is not annotated correctly, hence it was not picked for stable updates yet. I wonder if we should try to submit to linux-stable for v5.4 v5.8 series. -- 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/1935846 Title: Sony Dualshock 4 usb dongle crashes the whole system Status in linux package in Ubuntu: New Bug description: The hid-sony driver has custom DS4 connect/disconnect logic for the DS4 dongle, which is a USB dongle acting as a proxy to Bluetooth connected DS4.

I assume you were referring to LTS kernel 5.4 used in Ubuntu20.04. I compiled a kernel with the proposed commit in below link.
