[Dri-devel] TCL lockups with Tribes 2

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi all.
I've been testing the latest TCL drivers recently merged into the main 
cvs trunk thing (sorry I don't quite understand cvs) with various 3D 
apps, and I'm getting lockups with Tribes 2, after about 5 seconds of 3D 
rendering (not enough to actually play anything). The lockups seem to be 
dependant on the time since rendering started more than anything else. I 
have tried various levels and with sound on / off.
3D screensavers & Quake3 work fine, but I can't get any action from 
Tribes2. I have to ALT-SysRq (SUB) to sync, unmount and reboot each time.
I am using a 1600XP Athlon with 256MB DDR Ram, on an Epox (8KHA+ or 
something like that) motherboard, with a Via KT266A DDR chipset and a 
64MB DDR Vivo Radeon (and an SB Live 5.1).

I have successfully run the Mesa4 branch with Tribes 2 without lockups, 
but have had the same problem with every TCL checkout I've tried (sorry 
I didn't report this earlier - I didn't think the TCL stuff was stable / 
complete enough to bother complaining about something like Tribes 2).

I don't currently have another linux box here which I can use to log 
into this one and get any info (it that is at all possible) after a 
crash, but it someone thinks it will be handy, I'll get my friend's PC 
around here (I will need instructions).

 From 2.4.14 (I think) to 2.4.19-gentoo.
I don't think it's the kernel.

Any hints on how I can get this thing stable (or help you guys to) 
greatly appreciated!
