-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I''ve recently managed to get a 2.6.7 dom0 to boot without any major problems. I had seen the hwclock issues and the nosegfixup issues fly by and these seem to be all worked out now. Another issue though is still lingering for me, and I''m a little clueless as to how to go about debugging it. It seems that once I log into my gnome session, everything is aok for the first little while, until eventually I get a segfault pop-up for wnck-applet. I''ve never seen this segfault before, and am not sure if it is xen or 2.6.7 related (I''m still running a 2.6.1 variant). However, a few seconds later, whether or not I click the ''ok'' in the segfault dialog, the machine seems to lock hard. I''ve tested this w/ & w/o both a) removing the /lib/tls directory and b) the nosegfixup kernel option. Has anyone else seen this? or possibly know of any other cause for this? I will try updating to vanilla 2.6.7 tonight to see the issue remains. Also: A while ago, I tried building the xenolinux-2.6.7-dom0 kernel with a pentium II cpu target. The system appeared to boot up properly, however X couldn''t start as there seemed to be a mysterious SIGBUS being sent. For now, I''m using a PIV build on this PII..

The other way around I could sort of understand... xen/linux 2.6.7 hasn''t been as well tested as 2.4.26, but it seems to survive LTP (Linux Test Project) OK.

A ''debug=y'' build of Xen might help.I''ll hopefully be able to try something eventually. I just moved, so at this point I''m living out of cardboard boxes 8) Out of curiosity, is there any way to get the Xen console/crash dumps on the console (as opposed to serial)?> > >>A while ago, I tried building the xenolinux-2.6.7-dom0 kernel with a >>pentium II cpu target.

The other way around I could sort of > understand...Ah, I just checked my latest build, and it is in fact a PII build. I saw this issue a couple days ago: I may have had an inconsistent build.

If you''re in a graphics screen mode I''m afraid there''s no way to get crash messages out of either dom0 or Xen. If you''re in a text mode, you should see crash dumps from dom0. You are much better off with a serial line, though.

Adn Xen''s trace buffer can be seen with xen_dmesg.py. But if you''re locking hard then you want those crash dumps to get written somewhere synchronously, and there''s no better option than a serial line. :-) -- Keir ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ Xen-devel mailing list Xen-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xen-devel
Btw, Xen boot output can be collected by "xm dmesg" - xen_dmesg.py is dead.
