https://bugzilla.kernel.org/show_bug.cgi?id=215175 Bug ID: 215175 Summary: thunderbolt: consistent system freezes with Dell U4021QW, general protection fault, probably for non-canonical address 0xdead000000000108, Workqueue: events tb_cfg_request_work [thunderbolt] Product: Drivers Version: 2.5 Kernel Version: 5.15.5 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: leho@xxxxxxxxx Regression: No I haven't been able to identify any specific pattern to reproduce it. After a while into any given session connected to this DELL U4021QW 5k2k monitor, GPF is triggered, soon hanging all operations and requiring a full reboot. Any thoughts on what to try or test here would be very welcome, as this is a show-stopper for work. Context: machine otherwise works perfectly fine on various USB-C monitors, like DELL U4320Q and U4919DW, which otoh might not have relevance to these latest uberpowered Thunderbolt screens like U4021QW. nov 30 14:13:24 papaya syncthing[1559]: ... nov 30 14:18:09 papaya kernel: general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] PREEMPT SMP NOPTI nov 30 14:18:09 papaya kernel: CPU: 0 PID: 95013 Comm: kworker/0:4 Not tainted 5.15.5-gentoo+ #52 nov 30 14:18:09 papaya kernel: Hardware name: Dell Inc.
