>Description:
I have a problem with the disc controller during booting. Sometimes it's okay, but usually it fails. This problem is new with i386 6.3-RELEASE. I never had problems with older releases.

Here is the output of dmesg when everything is fine (verbose boot):

..
atapci0: <Intel ICH5 SATA150 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x3

ata1: reset tp2 stat0=50 stat1=00 devices=0x1<ATA_MASTER>

When it fails, I see lots of messages

..
ata1: stat0=0x80 err=0xff lsb=0xff msg=0xff
..

scrolling up very fast and finally:

ata1: reset tp2 stat0=80 stat1=80 devices=0x0

Later on the disk is not found and the kernel can't mount the root file system.
The computer is a Shuttle XPC-G2 with FB61 mainboard and Intel82865G + 82801EB chipset.
>How-To-Repeat:
The error occurs most of the time. After maybe half a dozen retires the system usually comes up without problems.
