[Xen-devel] RE: "Old method" bootloader failing with large ramdisk

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

I guess I should add that this is with a linux-2.6.29
PV kernel so might be something there too.

And "not completely or properly" means that "/init"
can't be found (sys_access("/init") fails for the
large initrd
