[impact]
on specific Dell systems, with a specific usb bluetooth device built-in, the udev rule 'hid2hci' provided by the 'bluez' package causes an endless loop of uevents resulting from 'bind' or 'unbind' kernel uevents. These new events were added to the kernel after the 'hid2hci' udev rule was written.
[test case]
the specific Dell system is required to be able to reproduce this, or at least the specific usb bluetooth hardware included in that system.
Reproducing this is reportedly easy, for example comment 75 indicates it happens on every boot.
When this happens, any process monitor (e.g. ps, top, etc) will show the 'udevd' process using 100% of a cpu, and 'udevadm monitor' should show repeated 'bind' and 'unbind' events as mentioned in comment 39.
[regression potential]
as this alters what kernel uevents the 'hid2hci' udev rule processes, regressions would involve the affected usb bluetooth device failing to be set up, or otherwise not processing the uevents correctly.
[other info]
this is not fixed yet upstream, as of my last check, but has been submitted upstream as mentioned in comment 95.
