Quick summary from my point of view: Guennadi is the only report of this problem, though equally he's the only user I know with an Elsa AG GLoria Synergy. I have not yet managed to work out why this could be happening; = I had expected that disabling the card reset that pm2fb does on initialisation = would fix matters, leaving the card at its BIOS initialised state. But it doesn= 't, and sees to cause bad problems. PM2_FIFO_DISCONNECT doesn't seem to me to bring much to the party. Since = we now have an example of it causing breakage, I agree with Guennadi that it sho= uld be marked 'dangerous'. I've been away from home/internet connection for some= time; I'm back on Tuesday and I'll submit a patch to do that ASAP. --=20 Jim Hague - jim.hague@acm.org Never trust a computer you can't l= ift. ------------------------------------------------------- This SF.Net email is sponsored by Yahoo.
