/usr/src/sys/i386/i386/local_apic.c and status of ULE
Hi all, I wonder, what is the status of the ULE scheduler? Is it supposed to work at all? I upgraded my -stable system some time ago and it started to hang at the end of the boot process, right before the mounting of the root device. I found out that the immediate cause was a change in /usr/src/sys/i386/i386/local_apic.c. I attach a patch that reverts the change, so that you can see what I am talking about. However, it only hangs if I use the ULE scheduler. That's why I wonder whether the ULE scheduler is supposed to work or not. Now, I understand that it might very well depend on some additional local condition. Thus, I also attach my dmesg (of a successful boot) and my kernel configuration file. best regards, Viktor -------------- next part -------------- A non-text attachment was scrubbed...

Hi again, Looks like the kernel configuration and dmesg where removed from my post; I guess I violated the attachment policy. I put them on a webserver instead: viktor.fi/attach Sorry for the extra noise.
