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.
