Comment 1 Matthias Bayer 2006-05-08 07:22:55 EDT
forgott about that one:

xen output on serial console show that version is 3.0.0 instead the one under
the 2107 kernel 3.0.2-2 !
Comment 2 adhisimon 2006-05-08 13:33:28 EDT
Confirmed. I've also got the same problem.
Comment 4 Mark Drago 2006-05-20 13:51:42 EDT
Just a heads up - I have upgraded to the 2.6.16-1.2118_FC5xen0 kernel that is
currently in updates-testing and this is now working again.
