My appologies for such a long e-mail, but here is an interesting problem
which has had me stumped for a week that I would appriciate some suggestion
on.
Recently, I upgraded to a new PCI motherboard, UMC chipset, Am586-P75
133MHz CPU, Diamond Stealth 64 (S3-Trio64V+) with 2MB DRAM, and an Adaptec
AHA-2940 (see dmesg output below for more specific info). At the same time
I upgraded the hardware, I also upgraded XFree86 in my FreeBSD 2.1.0
installation to 3.1.2D since it fixed some S3-Trio64 bugs.
Right away I started to have problems with the X server (XF86_S3) locking
up the computer. When X starts up there is a flurry of disk activity, the
sometimes the screen will change to my default background color, other
times the screen would flicker and then the machine would hang. In all
cases I noticed the disk access light on my external hard drive was always
on (even thought there was no continued disk activity) and remained on
until I reset the machine. I rummaged the archives at www.FreeBSD.Org to
see if there was any similar reports. I noticed several discussions
regarding conflicts with the serial I/O (sio) code and S3 graphics cards.
So I downloaded sio.c from FreeBSD-stable, modifyed my config file and
rebuilt the kernel. Problem still occurs.
Heres the kicker...
I noticed a pattern to the success and failures that occured. The first
time you run the 3.1.2D S3 server you get a warning message with a 10
second delay before the server starts up. When ever this delay occurs, X
will successfully start up with my configuration. If I shut down the server
and restart it the server will hang. If you remove the '.X' file created by
the 3.1.2D XF86_S3 server before it is restarted the server will
successfully start up. I was able to verify this by removing the '.X' file
prior to executing startx. Every time this file is removed, X will start up
without a problem!
At present I cannot find anything obviously wrong with my configuration
(see dmesg and X output below). The system runs fine under Windows and
appears to operate fine with my work around. Is there some obscure timing
thing or dependency that I am not taking into account here? Does anybody
have any suggestions on how to solve this problem (e.g. upgrade to
FreeBSD-stable)?
Thanks
Greg Shaffer
