Problem with SATA2 and Intel 82801EB
 

Hello,

I've recently purchased a WesternDigital SATA2 drive. My motherboard is a GigaByte GA-8IPE1000 with Intel 82801EB SATA controller. The problem I'm having is during the boot operation and mounting of the SATA disk. When I boot the system it slows down during the SATA (/dev/hde) identification. My kernel is 2.6.15.1

When I try to mount a /dev/hde partition I always get a "Disabling IRQ #11" warning and the mount is completed with a delay of 10 seconds. Note that the mount is being done but only after the delay.

If you need the full dmesg and lspci output please say so. I haven't included it since they are long.

problem solved!
 

Since noone had a clue about what was the problem, i just wanted to say that I still don't know why the sata hdd failed to work properly under 2.6.15_1. However I just tried 2.6.16 stable version and without modifying anything the drive is working perfectly.
