Hello, I have just upgraded to 4.3-RELEASE a machine based on a Gigabyte 7ZX motherboard (KT133 chipset, VIA 686A ATA66 controller). Since that moment, when I stress the disk with many writes (for example, untar an large archive), the kernel complaints with these messages: ata0: resetting devices .. done ad0: WRITE command timeout tag=0 serv=0 - resetting The disk ATA mode does not fall back to PIO; eventually, the untar finishes. Surprisingly, if I enable write caching the problem seems to dissapear. Maybe I did not see this problem with 4.2-RELEASE because WC was enabled by default. I did the same tests on other machine with the same motherboard and processor (Duron 800MHz), but different disk, and everything works fine. These are the relevant lines of dmesg output on the problem machine: atapci0: <VIA 82C686 ATA66 controller> port 0xffa0-0xffaf at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 .... ad0: 19546MB <FUJITSU MPG3204AT E> [39714/16/63] at ata0-master UDMA66 acd0: CDROM <LG CD-ROM CRD-8522B> at ata1-master using WDMA2 Bad disk firmware?
