Hello there, I have been having a lot of trouble with my ITE 8212 RAID controller after upgrading from kernel 2.6.18 to 2.6.26. I have posed to kernel trap and was advised to mail a copy to this mailing list. If anyone has any ideas on how to solve this problem i'd be extremely grateful. The post is located at http://kerneltrap.org/node/16482 and looks like this: IT8212 driver seems to be broken - no DMA or functionality in general August 10, 2008 - 3:20pm Submitted by Anonymous on August 10, 2008 - 3:20pm. Hi there, I am having some problems with my ITE 8212 raid controller. It was working (more or less OK) in version 2.6.18 but now appears to be broken in 2.6.25 and 2.6.26.2. My main issue is that I cannot turn on DMA with the drive. When the controller was working under 2.6.18, I had to enable DMA before mounting or even checking the drive as strange disk errors would occur which resulted in needing to reboot. First I tried the driver (it8212) in Device Drivers->ATA/ATAPI and friends->IT821X After booting, hdparm gives me the following error when I try to set DMA on the drive: HDIO_SET_DMA failed: Input/output error Dmesg also says the following during the boot: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ... ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 IT8212: IDE controller (0x1283:0x8212 rev 0x11) at PCI slot 0000:00:09.0 ...it821x: controller in smart mode.
