Googling, I can see that this has happened to others ... but: 1) It appears to be harmless 2) No explanation on what the actual bug is. http://forums.fedoraforum.org/showthread.php?t=153310 ( Yes, I am in that thread too ). The warning / error message appears just after "Uncompressing linux", and it only started after FC6 kernel 2.6.20.2944. Kernels prior to that does not show the warning / error message. It would be good if someone could explain what the actual bug is. Looking at the hp site ( I have a Compaq Presario V6107AU notebook ), the only updates to the version of BIOS that I have is for Vista-compliance. Can anyone explain what it means ? Regards, John
