I guess that explains the second problem. I'll get a POWER6 machine and try it again.</span></div><div><br><span></span></div><div><span>But for the first problem, i'm pretty sure i'll be able to reproduce it again, even on POWER6, as it doesn't really have anything to do with the arch. </span>LOAD_BUFFER_SIZE is just not large enough. I didn't use the RHEL yaboot, i simply compiled it from the tar.gz on the yaboot page. Although RHEL6 uses an older yaboot, 1.3.14, in which LOAD_BUFFER_SIZE is even lower, if i remember correctly.</div><div><br></div><div>I'll retry it on POWER6 with the default value and debugging as soon as i can.</div><div><br></div><div>Thanks,</div><div>Radu<br></div><div><br></div><div style="font-family:
