I reproduced this with vanilla 2.6.12.2 now, and I'm quoting the entire message for the benefit of the guys over at linux-poweredge@dell.com To make it short, the suspend/wakeup loop didn't occur with 2.6.12.2 vanilla. Still the bug happens, the box is apparently usable, but not for the remote administration, so usability is quite shaky a definition ;) The relevant stuff is still at the url below, the two new interesting files are: http://mjt.nysv.org/kernelbugfest/usb_bug_2.6.12.2.ksymoops http://mjt.nysv.org/kernelbugfest/netconsole_panic_2.6.12.2 (The netconsole issue is probably not related and I'll look into it later, if ever, as we're not really using it...) I also got a hint that disabling power management might help, but that has to wait until tomorrow.. Anyone want to back this theory? :) Thanks! --=20 mjt --tEHm/81IqsjXUEYk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) iD8DBQFCzTA9IqNMpVm8OhwRAu7KAKC4bAv969mfXJdqlbDw3TjKFjAvDACfYKHo yc+lOJp4QVgqwKgap+DwBEk= =s0fF -----END PGP SIGNATURE----- --tEHm/81IqsjXUEYk--
