Hello all,
I'm having some issues booting rhel6 with yaboot.
1) In order to boot the rhel6 kernel i had to increase LOAD_BUFFER_SIZE to 0x2600000 in fs_of.c, as the ramdisk is simply too large and it would not get all downloaded over tftp.
2) After i got rhel6 to work, i tried the rhel6.1 kernel and this one fails. The following is the copy paste of what i see:

<Tab>/<Alt-Tab> between elements | <Space> selects | <F12> next screen
At this point i should be able to select which adapter i want to use but the machine gets stuck and needs to be manually rebooted.
I encountered this behaviour before, when trying to get rhel6 to work, and when i chose too high values for LOAD_BUFFER_SIZE.
My yaboot conf file looks this this:
message = yaboot.msg
timeout=30
default=linux6
image=rhel6ppc/vmlinuz
initrd=rhel6ppc/ramdisk.image.gz
label=linux6
append="ks=nfs:192.168.205.226:ks-rhel6ppc.cfg br=192.168.205.226:2217"
Any help would be apreciated.
Thanks,
Radu
