Obviously I can only comment on my own hardware but the machine has been used constantly since Thu Jul 12, its now Jul 30 and I havent had a single IDE related problem. As a hobby, i use the machine for DigitalVideo, and regularly grab 20-30GB from my capture card, then process it, which means the IDE bus gets a lot of use and seems to be an ideal situation for the data trashing problems to rear their ugly heads (no pun intended) but, as i said, I haven't seen any here. DRAM Prefetch makes my sound usuable, as the VIA fixups for the SB cards do not work here, and for (at least) two other people who i have had email correspondancy with. -- Regards, Gavin Baker - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
