I've found that to build and boot an upstream kernel on RHEL5, it is necessary to specify: CONFIG_SYSFS_DEPRECATED=3Dy CONFIG_SYSFS_DEPRECATED_V2=3Dy Without these, I was seeing a highly similar result booting a 2.6.34 kernel on a RHEL5 guest. Apparently, something in nash or something that nash uses doesn't work without some deprecated symlinks in sysfs and the resulting error looks like a bad initrd. http://cateee.net/lkddb/web-lkddb/SYSFS_DEPRECATED.html=20 Anecdotally, I've also found that using make -j4 doesn't always seem to work, so I always leave off the -j4 (possibly especially in "make -j4 modules modules_install"). Perhaps one of those will help? > -----Original Message----- > From: Jeremy Fitzhardinge [mailto:jeremy@goop.org] > Sent: Thursday, May 27, 2010 11:31 AM > To: Min Lee > Cc: Xen-devel@lists.xensource.com > Subject: Re: [Xen-devel] xen-unstable + pvops-kernel doesn't boot on my > machine, ibm x3550M2 >=20 > On 05/27/2010 09:10 AM, Min Lee wrote: > > Hi, Jeremy. > > I'm attaching full boot log for both working/non-working case. > > The working case is xen-unstable+linux2.6.18.8 and it boots up, at > least. > > Nonworking case is pvops kernel native. >=20 > That just looks like your initrd isn't set up properly.
