Hello Tejun,

I have taken more detailed dmesg outputs of three configs with ATA_DEBUG and 
ATA_VERBOSE_DEBUG defined. You can find them at this address:

http://cekirdek.pardus.org.tr/~faik/tmp/ahci/

* ahci file is the output of CONFIG_SCSI_SATA_AHCI compiled config
* noahci file is the output of CONFIG_SCSI_SATA_AHCI not compiled config
* ahci-nullsoftreset is the output of CONFIG_SCSI_SATA_AHCI compiled config
but given NULL to softreset parameters of ata_do_eh in ahci.c

Also poweroff-config is the used .config file. Only CONFIG_SCSI_SATA_AHCI is
changed between them.

I am not familiar with AHCI nor ATA internals. So please ask if you would like 
to see anything more.

Regards,
- Faik
