I have been working on a fix for this which works for older glibcs that panic when the new relocatable VDSO is used. However, I believe at this time that the fix is going to be too radical to consider at this stage in the release of 2.6.21. We don't expect this config option to be turned on by vendors for new distributions, so at this point we are willing to drop support for it when VMI is compiled in, and work on a patch for 2.6.22 which more fully addresses the problem. Please apply, thanks. Zach
