            Bug ID: 215890
           Summary: Regression in 5.18: bcm5974 trackpad causes error:
                    xhci_hcd rejecting DMA map of vmalloc memory
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.18-rc4
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: satadru@umich.edu
        Regression: No

The Apple BCM5974 trackpad & keyboard show up in sudo libinput list-devices
when booted into 5.17.4.

In 5.18-rc4, the keyboard works, but the trackpad does not. libinput
list-devices shows the keyboard, but not the trackpad.

This error shows up in dmesg:
