Subject: 2.6.19-rc2-mm2 AHCI lengthy pause on detection
Date: Wed, 18 Oct 2006 11:26:51 -0600 [thread overview]
Message-ID: <453663DB.5060908@gmail.com> (raw)
AHCI pauses heartily on during detection boot, but eventually proceeds.
This problem currently exists with 2.6.19-rc2-mm1, but did not exist
in 2.6.17.3. I realize that's a huge gap, and if you'd like me to
narrow it down, I'll be glad to try.
Messages surrounding the hang:
scsi2 : ahci
ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata2.00: qc timeout (cmd 0xec)
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x104)
ata2: port is slow to respond, please be patient (Status 0x80)
ata2: port failed to respond (30 secs, Status 0x80)
ata2: COMRESET failed (device not ready)
ata2: hardreset failed, retrying in 5 secs
ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata2.00: ATA-6, max UDMA/133, 640 sectors: LBA
ata2.00: ata2: dev 0 multi count 1
ata2.00: configured for UDMA/133
I should note that on this system ata1 and ata3 both detect quickly, but
they have 1.5 Gbps devices whereas ata2 has a 3.0Gbps device.

dmesg snip from 2.6.17.3, without the hangup:
