Re: Network bridge on current.
I am wondering how to do network bridging on current. The description in the handbook seems to be out of date as the sysctl IODs are no longer in evidence. Does loading ng_bridge substitute for building the kernel with OPTIONS BRIDGE? Excuse my ignorance (and curiousity), but wouldn't it be cheaper to just buy a switch? Cheers, -Peter S.

My last good kernel was from aug 14. On a kernel from 09/05, I get a
page fault as soon as I try to play mp3s using mpg123.
Note that I have an Aureal Vortex 8830, so I have to use the linux
drivers to get the device working
(http://www.cis.ohio-state.edu/~matey/au88x0/) so this might just be a
problem with interactions between the linux .o files and kernel data
structures. The soundcard worked fine using the linux drivers on a
-current from August 14. I'm wondering if anything changed in the pcm
code since then.
Here's the page fault in DDB. I have a debug kernel if anyone needs
more info.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x101b
fault code= supervisor read, page not present
The pcm interfaces did change. The following patch fixes the au88x0
driver for me.

Re: emacs / ncurses - problem somewhere
Ever since the libtermcap / libncurses consolidation, change emacs has problems positioning the cursor and properly updating the screen for character-only devices like the console. It also affects the display in an xterm in non-X mode, i.e., when DISPLAY is *not* set. This is emacs 20.4, by the way on current as of yesterday. I've tried emacs from packages as well as a freshly built one from the ports and both exhibit the problem. Note that emacs works fine when it brings up is own window due to DISPLAY being set. Has anyone else seen this and already have a fix or know for sure whether this is an emacs bug or a FreeBSD bug? I filed a bug report for this. I fixed it in Emacs with the following patch. I think it's a FreeBSD bug, though. -Peter- [EMAIL PROTECTED] --- /tmp/tparam.c Fri Oct 29 12:27:03 1999 +++ tparam.cThu Oct 7 23:07:24 1999 @@ -290,6 +290,9 @@ case 'D': /* %D means weird Delta Data transformation. */ argp[0] -= 2 * (tem % 16); break; + case 'p': /* from terminfo */ + p++; + break; } } else To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
