--- Comment #6 from Friedrich Gräter <[EMAIL PROTECTED]> 2008-10-30 06:21:42 PST --- Okay, I did some further investigations by myself. It seems to be a bug in the AtomBIOS code, that will be executed when unblanking the screen. It could be also a bug in the interpreter. I put some trace-code into the AtomBIOS byte code interpreter which tells me, what the AtomBIOS is doing. I found out, that it hangs in an endless loop, executing the following instructions: 0xEE9335BC Op-Code 0x4A | Test 0x9, AtiReg(0x1827+0x200) 0xEE9335C1 Op-Code 0x44 | Jump [Equal] These two instructions are executed in the endless loop. The Value of AtiReg(0x1827+0x200) = 0x2. I try to figure out now whether it is a bug of the firmware or a bug in the processing of the jump-instruction by ProcessJump. (It's a little bit time-intensive, because I've to reboot my computer during each test) -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
