Re: build with SMP causes (multiple?) issues on my system

Eric Haug pointed out what my problem was to me, and I just noticed that he had posted to the list about this causing issues for some people on Aug 1 entitled "SMP freezes when ttyd0 getty started". Thanks Eric, sorry I missed that post to the newsgroup.

This has allowed the machine to finish starting up, and get to a login prompt.

Interestingly enough though, when booted into single-user mode with SMP enabled, the system still has issues with the Syncing discs part, described here:
(note: it does not have this problem normally, even with SMP, but only in single-user mode.)

So, I went back in (after some aggrivation with booting the computer from a livecd, since vi nor ee wanted to agree with me when in single-user mode, but that's a side story), and removed the SMP from the kernel config, rebuilt it, and rebooted, and ran into my second issue. Upon trying to reboot (from single-user mode while SMP was enabled in the kernel), it attemped to perform the normal "Syncing discs .. " followed by numbers, often eventually repeating the same number over and over, and gives up. It prints out the messages:

giving up on 1 buffers
Debugger("Busy buffer problem")
CPU1 stopping CPUs: 0x00000001
Stopped at      Debugger+0x23:  mob    $0,in_Debugger.354

and then it enters the debugger (the same one from hitting ctl+alt+esc). Now, when I was talking to GeekGod, it was suggested that I type "panic" followed by "reset". So, I tried typing "panic" and was greeted by a very interesting screen of text which probably makes sense to someone, and the line "CHKTOKEN loop 1" repeating over and over and over. At this point GeekGod suggested that I really need to send a bug report in, and that pretty much brings this up to speed.
