David, could you please test whether > tip/master works for you out of box? ===== SHELL OUTPUT (for sanity) ===== commit e3fc96d5aca609bcf6ab0327850a109df65c1dbb Merge: 6b8c836... a36d241... Author: Ingo Molnar Date: Thu Aug 28 22:57:20 2008 +0200 Merge branch 'x86/core' ===================================== Results: both ECS AMD690GM-M2 machines boot fine... - no need for "hpet=disable" - no error messages in 'dmesg' (except that annoying TSC b.s.) More good news: the user who first reported the regression in May (he uses Intel Q6600 CPU + Abit F-190HD mboard, while I use AMD Athlon 64 X2 3600+ CPU + ECS mboard) posted a followup on his blog: ===== http://ciaranm.wordpress.com/2008/05/18/yay-for-git/#comments ===== Oh good. Looks like git head works just fine now for me, so whatever it was appears to be fixed. Comment by Ciaran McCreesh — August 26, 2008 @ 6:25 pm ========================================================================= I was afraid that Yinghai's original patch (many days ago) which worked for me was too AMD-specific, and would not work for this other user experiencing the regression against commit 3def3d6d... When you (Ingo) and Yinghai made it more generic afterwards, I feared that it was too HPET-specific. I tried to get Ciaran here, so that the problems he and I were having could both be solved. It's not clear what change solved his regression -- clearly it's not today's patch, since his blog post is dated 2 days ago! -- but I'm glad to see that all is well in the world again. Ingo, could you do me a favor? Mr. Anvin's inbox got badly messed up because of me: > From: H. Peter Anvin [...] > Sent: Thursday, August 28, 2008 8:21:09 PM [...] > This may be a rehash of things previously discussed in this thread; my > email seems to be a bit flakey to the point that I don't know if I have > gotten all the messages. Could you explain this to him for me? I don't want to post any more than this one message, just making a bad situation worse. (Sorry about the threading, Peter!) Since Monday I have gone back to work on my LAN. RAID was quickly set up on the fileserver, but the backup of the P4 isn't finished so I _still_ haven't been able to pull the hard disk from it for the webserver. Only after that will I be able to get the MTA arrangement I want, and banish this webmail client FOREVER! (I should have done all of this while I was helping you troubleshoot the regression, since my 2.6.25 kernels work fine, but I was too excited about being able to help to think that clearly.)
