I have an HP nx6125 that will randomly hang if powerd is enabled and if you search back through the mailing lists, there are a few other people with similar problems. I've done some experimenting and in my case, it's the clock speed transitions that cause a hang. The actual clock speed is irrelevant. I believe it's a race condition or a timing bug. --=20 Peter Jeremy --MIdTMoZhcV1D07fI Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFFitIf/opHv/APuIcRAidDAJ9buD1UhHRSzk6sEpgrn1JxuivV/wCcDjt/ CJa+6V24g36Rvm759JuMCGk= =yX/i -----END PGP SIGNATURE----- --MIdTMoZhcV1D07fI--
