I just updated to RELENG_7 from 6.2 and I'm running into some really annoying issues with jerky mouse movement and skipping sound. This seems to be similar to: Re: SCHED_4BSD in RELENG_7 disturbs workflow This happens both with 4BSD and ULE. I seems to happen when I'm compiling ports and a new cc/bzip2/sh process fires off (I'm just watching top), I'll get the skip/freezeup. This behavior is pretty pronounced, as I'm installing gutenprint right now....

...hild -- 37126 was (v)forked to launch a compiler or some such and remains stuck in between (v)fork and exec somewhere... The OS is: FreeBSD 7.0-STABLE/amd64 from Sat Jul 26, 2008 and the box is otherwise perfectly functional. The scheduling-related options are set as such: options SCHED_4BSD # 4BSD scheduler options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions Let me know, what else I can do to help fix this bug -- I'm going to reboot the machine tonight... Should I switch to SCHED_ULE as a work-around? Thanks! Yours, -mi

Hi Jeff, I have a single-CPU system with P4 HTT-enabled processor (7.1-RELEASE-p3), kernel compiled with SCHED_ULE. Copyright (c) 1992-2009 The FreeBSD Project.

Hello! My attempt to build openoffice.org-3 seems to be hanging. Pressing Ctrl-T produces: load: 0.11 cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k (tcsh is used by OOo's build-script). What is this "sleeping without queue" state, and why is process in it for so long? This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is currently in use and

...(counted from AGP slot on) made things clear, but using both NICs together (either additional fxp0 or the new em0) remains the systems completely unstable. In FreeBSD 5.1-RELEASE-p2 and especially in FreeBSD 5.1-CURRENT this 'gambling' seems to reach its climax. My kernel is built up with SCHED_4BSD because SCHED_ULE and ADAPTIVE_MUTEXES crashes immediately the same way as described (running a while, then coredumping or freeze at the stage after the amr0-RAID showed up in the kernel boot messages, see the dmesg output below). I'm not an hardware expert, but all this wierd stuff looks like...

Hi, during some big discussions in the last monts on various lists, one of the problems was that some people would like to use freebsd-update but can't as they are using a custom kernel. With all the kernel modules we provide, the need for a custom kernel should be small, but on the other hand, we do not provide a small kernel-skeleton where you can load just the modules you need.
