I have a machine here, still running 2.2.5-RELEASE, and regularly test loader on it. To double-check, I just upgraded the bootblocks to 2.2.6, and loader works fine. Because loader runs under BTX, the protected mode environment passed by the bootblocks is completely torn down, and the machine is brought back to real address mode before BTX starts. So I just can't relate to this kind of cause producing this kind of effect. To answer David's original question, I don't know of anything likely to cause loader to behave this way. I think Daniel's suggestion, made elsewhere, of trying /boot/loader.old would help in establishing whether the problem is in the new code, or whether something in the environment has changed and is causing problems. However, I'll try the latest loader, once today's make world finishes here. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
