Guillaume: I believe I've fixed this problem in the just released hal
0.2.97, at least it works nicely with my PCMCIA card reader which showed
the same issues. I see that you are running Fedora Core development;
updated hal-0.2.97 packages should appear in rawhide soon [1].

It would be great if you can test these packages ('rpm -q hal' should
report hal-0.2.97-1 or higher) and if it fails then please report the
bug to http://bugzilla.redhat.com or the hal@freedesktop.org mailing
list. If it just works, also feel free to mail me personally; I would
appreciate it! Thanks.

Hotplug folks: I'd just like to note that this problem is not exclusive
to hal at all, it even applies to mount(1) if the filesystem given is
'auto', cause then mount(1) access the device file and this will cause a
hotplug removal and then a hotplug add. Specifically, using udev
callouts to get the drive serial number or volume lanel will also cause
infinite loops.

Can anyone please confirm this is a bug in the IDE subsystem?

Thanks,
David
