[Xen-users] Centos5.1 x64 kernel works, x64xen doesnt. Fails with repeated "drive appears confused".
Not sure the proper etiquette for this, but since I dropped a dmesg dump over on CentOs I thought it would be more polite to post a link to it here, rather than posting it all here too. My problem is that running the x64 xen kernel on Centos5.1 causes weird failures of my cdrom. It seems that the xen kernel isn''t mapping interrupts properly, and it also seems to be failing to read the e820 information. As a noob I have no idea if this is related. The dmesg reports "BIOS bug", but the BIOS seems to get it right in the non-xen kernel. I have an intel 5100 chipset, supermicro X7DCL-i mobo. The link to the Centos forum post is: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=14476&forum=37 I think CentOS 5.1 is xen 3.0.3...

Ok, the BIOS bug is a bit of a red herring - xm dmesg shows xen getting the e820 info correctly. I just needed to learn how to build kernel modules so I could update to the latest kernel and build my ide driver. Appears to work now. Jamie PS Yeah, its 3.1.0. -- View this message in context: http://www.nabble.com/Centos5.1-x64-kernel-works%2C-x64xen-doesnt.-Fails-with-repeated-%22drive-appears-confused%22.-tp17551487p17572247.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
