Description Lachlan McIlroy 2010-01-29 04:24:49 UTC 
Description of problem:

Installing RHEL 5.3 or the recent 5.4 beta onto a z200 prototype workstation shows some curious activity in /var/log/dmesg regarding the negotiation/setup of SATA components.

The messages in dmesg indicate that the negotiations between the controller and the drives had some initial failures but settled in at UDMA/100.  Here's the snippet from the file:

"ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: ACPI _SDD failed (AE 0x5)
ata1: failed to recover some devices, retrying in 5 secs
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: ACPI _SDD failed (AE 0x5)
ata1.00: ACPI: failed the second time, disabled
ata1.00: configured for UDMA/100
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata2.00: ACPI _SDD failed (AE 0x5)
ata2: failed to recover some devices, retrying in 5 secs
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata2.00: ACPI _SDD failed (AE 0x5)
ata2.00: ACPI: failed the second time, disabled
ata2.00: configured for UDMA/100
ata3: SATA link down (SStatus 0 SControl 300)
ata4: SATA link down (SStatus 0 SControl 300)
ata5: SATA link down (SStatus 0 SControl 300)"

The read performance, measured using 'hdparm -t', is ~75 MB/sec, so it seems that the SATA hard drive connection is running ok.  The HDD is capable of 3 Gbps so I'm concerned that, perhaps, the driver has not gotten the SATA bus speed set optimally.

Version-Release number of selected component (if applicable):
RHEL5.3 or later

How reproducible:
On every boot.

Lachlan,

Would you please verify kernel-2.6.18-185.el5.bz559815_2.1 test kernel? Thanks.

dmesg from booting with 2.6.18-185.el5.bz559815_2.1

This is the dmesg from booting with the test kernel from comment #5. Looks good to me!
Comment 7 Lachlan McIlroy 2010-02-02 00:48:54 UTC 
Yes, looks good.  The output is identical to what I got with -186+patch.
Comment 9 David Milburn 2010-02-03 00:19:08 UTC 
David, Lachlan, thanks for the quick feedback.
Comment 10 David Milburn 2010-02-03 14:11:16 UTC 
dwa, any chance you could boot up a RHEL6 kernel? I think you should be able
to reproduce the same problem. If so, we could open up a seperate BZ for
RHEL6.
Comment 12 RHEL Program Management 2010-05-20 12:46:38 UTC

products.  This request is not yet committed for inclusion in an Update
release.
Comment 14 Jarod Wilson 2010-05-25 21:11:36 UTC 
in kernel-2.6.18-200.el5
You can download this test kernel from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
