Well, I'll voice 'em so everyone can hear. I *HATE* that thing's name. C6 AKA Winchip! *WINCHIP!* Oh, and supposedly, it puts out a LOT of heat, and responds BADLY to high-speed bus (ie; 75MHz, 83MHz). But I haven't used one, so I can't confirm or deny this. ;P
#The Centaur preliminary databook explicitly lists the TSC bug (and gives #the div by 0 in Linux as the known problem they cause). It states it is #fixed/will be fixed in stepping 1. No workaround is provided in the datasheet #I have. Its available from in PDF from www.winchip.com
Okay, so then all we really have to do is worry about C6's @ stepping 0. Now, that leaves the Cyrixes. I think I'll have to drop 'em a line today sometime, and see what they've got. I'll also have to try and grab an updated databook, but it's unlikely I'll have a hard copy. (I am NOT printing out all 180+ pages on a fscking inkjet! Somebody donate a laser printer or a fast dot matrix!;) However, IIRC, they HAVE updated the 6x86MX databooks recently, and I believe they DO mention this issue now. (They better after I screamed at 'em for over a week.};)
Ugh, where's my coffee? (I have to fix X first.:P)
