kernel 5.4 bug with dock WD19DC and BIOS 1.9 : invalid opcode: 0000 [#1] SMP NOPTI
Hello,
I'm experiencing full freeze of my Precision 7540 when plugging, unplugging the Dock WD19DC. I have to force reboot the computer by pressing the On/Off button for several seconds.
I updated the BIOS to 1.9 and the WD19DC drivers accordingly, but I'm still having the issue.
Please find below the kernel stacktrace below
