So maybe we need to lower the priority of the do_IRQ error from pr_emerg
to pr_err then ?  That will stop throwing the errors in the users face each
boot on distros which have chosen to set the quiet loglevel to such a level
that pr_err messages are not shown on the console (*).

*) Since there are simply too much false-positive pr_err messages in the kernel,
try e.g. plugging in a usb-stick and then do "dmesg -level=err"
Note the messages will still be in dmesg and in the system logs
