An interesting finding is the log also says "Opening tftp ... failed" although the booting is successful. That said the only meaningful message in the debug log is "error, couldn't send network packet". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Test the most up-to-date grub2 (bzr) trunk package to see if the problem remains? home:arvidjaar:grub2-next 2. Doing packet capture on the tftp server would be helpful, you can use wireshark $ tshark -i Btw, is this issue specific to certain hardware you have tested?

Nice. At least we don't have to solve the problem from scratch. :) We have to find that patch out and apply it, we can't use that (relatively) not stable latest trunk of grub2. It's even not public on openSUSE.

I hope it helps...

Can't we just ramp up factory grub2 to latest mainline code base and be done with it?

Yes. I think we will. Practically almost everything is done except for extensive testing.

...

No need to do that immediately if there still is SP3 work, but we should/will do that anyway.

Yeah, that's why we are working to find out the fixing patch from upstream to cherrypick.
