SuSE 9.1 and VIA VT8363 / 8365

Hello all. Can someone tell me if there is a problem with SuSE 9.1 and VIA VT8363/8365 ?? When i install SuSE 9.1, my computer gets very slow and its impossible to work with. but, when working in SuSE 9.0, its stays ok Would it be because of Kernel 2.6.x ??? Ive checked my Hard Drive, (it could be because of it), but is everything ok My Computer: AMD Athlon 1.2 GHz 512 SDRAM 160 GB HDD NVIDIA GFORCE 4 MMX-SE 64 DDR Someone has the same problem ?? PS: ive tryed with Fedora Core 2 (could it be something with SuSE 9.1), but the problem is the same... Kernel 2.6 ??? Regards Bruno Santos
