The service there is expected to be down for a while. I think I can get everything back tomorrow.
参与评论gjournal alpha released
gjournal is one of the Google Summer of Code projects that is FreeBSD related. It provides data journalling service that will be useful for frequent randomized area writing, just like write clustering.
Today, the first public alpha version has been released.
Please note that this is not intentional to replace SoftUpdates nor a real journalling file system, as the metadata consistency protection is different than just do data writing journalling. However, this indicates a good way of providing better performance for file systems.

参与评论ULE+SMP+PREEMPTION fixed, finally!
David Xu’s two recent commits against -HEAD has finally fixed ULE on SMP, PREEMPTION and FULL_PREEMPTION case. Both his and my stress tests has proven that ULE is now rock solid again.
Now we will focus on solving other issues. Please be sure to test our next 6-STABLE snapshot and provide feedback, so we can make a great 6.0-RELEASE!

Finally we got ULE fixed! After some observation about stability this would definately be MFC’ed to RELENG_[56].
UPDATE: This is proven incomplete. We are still under investigation.
UPDATE: A subsequent commit of David Xu has finally got it fixed.

参与评论通过Console Server连接控制台
Howard最近研究了一下Console Server，很好玩的说。Console Server是一种用于连接大量串口设备的设备，并且可以控制电源。这样调试kernel就方便多了。以前都是用直接连串口的方法。

So now we have 6.0-BETA, 7.0-CURRENT, and both are frozen for bugfixes. I would struggle with the SMP ULE issue.
