2.4.20-rc1 and udma with VIA kt8235

[Christian Guggenberger]

Marcello, Vojtech,

would you please incorporate the patch which lets udma work on a VIA kt8235 
Southbridge in one of the next 2.4.20-rc releases?
I know, it would work with 2.5 series but that's not an alternative for me now.

I have been using the following modification for a couple of weeks now to both 
the 2.4.19 and 2.4.20-pre11 kernels on an MSI KT3 Ultra2 board (has the 8235 
southbridge) and have not had any problems with the hard drives or DVD/CDRW 
drives in the system running in UDMA mode.

The code modification comes from a patch that was posted to the list a while 
back by Vojtech.

thanks,

I knew about that patch. I only wanted to point out, that it would be nice to 
see it in mainline 2.4.20, as the number of mobos with VIA KT400/8235 and 
KT333/8235 is increasing:-)
