>Description:
I am experiencing a long delay at boot time (more than 30 seconds) due
to the ATA subsystem when the probe routine looks for disks on the
VIA 82C686 controller. There are no disks attached to that controller
(the disks are attached to the Promise ATA100 controller) but the
probe routine hangs when determining that. My system has an ASUS
A7V motherboard. I have provided as much detail as I can below, but
I would be more than happy to get additional information (through
debugging or patches) if someone tells me what is needed.
Here is my analysis of the problem, from looking at the verbose
boot output and the source code:
The delay occurs just after the follwing output during the boot:
ata0: mask=03 ostat0=a0 ostat2=b0.
The delay appears to be occuring in the loop in the ata_reset()
subroutine - the busy bit is always set so we just keep going
through the loop. This occurs because the initial status0 and
status1 values are 0xa0 and 0xb0, which is clearly not what the
ata driver expects to see when there are no devices present.
Here is the ATA section of the kernel config file:
# ATA and ATAPI devices
device ata
device atadisk # ATA disk drives
device atapicd # ATAPI CDROM drives
device atapifd # ATAPI floppy drives
options ATA_STATIC_ID # static device numbering
options IDE_DELAY=6000 # set the probe delay in ms
Here is the dmesg output when I boot with the verbose option:
