My HP/Compaq V6107 still goes into a coma even with this patch. If I boot to single-user mode, it seems to happen immediately after the CD-ROM probe messages (which would be when the system becomes idle). Otherwise, it goes comatose whilst trying to load the entropy. I've re-applied idlecpu_apic_5.diff and it seems to work with hw.apic.idle_cpu=3D"1" (but see below). I've hacked local_apic.c to save the value read from MSR_C001_0055 and that shows that C1eOnCmpHalt is set. Worse,I've noticed that the RTC interrupt occasionally stops. I have worked out that I can restart it by writing to sysctl machdep.adjkerntz (which was the easiest way to issue rtcin(RTC_INTR) from userland). I presume that occasionally the RTC interrupt is lost and so never reset (as per the comment above rtcintr()). I haven't yet tried using the i8254 as a wakeup source. Any ideas on where to look next? --=20 Peter Jeremy --k+w/mQv8wyuph6w0 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGOcqv/opHv/APuIcRArx+AJ9rLDnzKS5jLsFqRdEarEXtQi214ACfRM0N ZrucYf6du8EuI35IjduzqCA= =vR3w -----END PGP SIGNATURE----- --k+w/mQv8wyuph6w0--
