If you mean something like the below, then yes. Thanks! [.]
All done. Good news (I think): there's no difference in the CPUrelated topology on either system with your patch, aside from kernel build date. The topologies are still detected correctly. In case you want them:
Thanks a lot for the test!

Before the patch, all the "SMP: AP CPU #X Launched!" were correctly displayed, with carriage returns. Yes, I use "options PRINTF_BUFR_SIZE=128". And I don't know if that's related to the patch. Cheers, Olivier

[test results snipped]

All other systems I have are C2D and C2Qbased, but I can't easily test on those given their production roles. If there's a particular Intel processor family/model you're interested in, let me know and I can dig around to see if I have access to one. Re: patch for topology detection of Intel CPUs 2
Re: patch for topology detection of Intel CPUs No particular models in mind. If you have systems with more complex topologies, like multiple physical packages or HTT enabled, I will be interested in seeing test results for those. Thanks again.

stable8 regression: time stands still
Source: http://unix.derkeiler.com/MailingLists/FreeBSD/stable/201003/msg00016.html
From: Ruben de Groot <mail25@xxxxxxxxx> Date: Mon, 1 Mar 2010 21:34:50 +0100
Hi, After upgrading my 7.2PRERELEASE system to 8stable I encountered some very strange problems, most obvious: startup would hang on starting devd, only continuing after a ^C reboot would hang, but reboot q would work. nfs clients would report strange locking problems. Now I've found that probably the real problem here is that NO TIME IS PASSING (!!). Successively calling 'date' will allways give me the exact same time to the second. A 'sleep 1' will hang indefinetely.
The BIOS is OK. After (and only after) a reboot, time will be updated to the time of reboot, but stay there forever after. Before I go back to 7.2 (tested there are still no problems there with a livecd) maybe someone want to shed some light on this. I've attached dmesg.boot. cheers, Ruben Copyright (c) 19922009 The FreeBSD Project.
