Notice that with 2.4.3 it *only* affects the disk on the PCI controller card; a similar ATA/100 disk on the motherboard's controller did not experience the slowdown. Also, FYI, I noticed the mention of VIA fixes in the -ac7 change list, but those changes did not cause or fix this particular problem. The problem occurs in all the 2.4.3's that I've tried: -ac5, -ac6, -ac7. BTW, It's not hurting me right now, because the disk on the PCI card hasn't been put to work yet. I just want to make sure you guys are aware of it.
