Comment (by waddlesplash):
The return value of PrepareKernelAccess is not checked here:
https://xref.plausible.coop/source/xref/haiku/src/add-
ons/kernel/busses/usb/xhci.cpp#2804
However, it is very curious this appears as a "user mapped address"; I
would expect InitKernelAccess to have made it into a kernel one (by
subtracting off the area base). The syslog tail should show what is really
happening.
