Summary: Kernel fails to properly identify SATA drives
Product: Platform Specific/Hardware
Version: 2.5
KernelVersion: kernels from 2.6.24 to 2.6.25
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: x86-64
AssignedTo: platform_x86_64@xxxxxxxxxxxxxxxxxxxx
ReportedBy: chiwihouse@xxxxxxx
Latest working kernel version: 2.6.22.9 and 2.6.23.17
Earliest failing kernel version: 2.6.24
Distribution: Ubuntu x86_64
Hardware Environment: Asus M2R32-MVP 580X SB600 (AM2)
AMD X2 4000+
4GB DDR2
SATAII HDD
SATA DVD R/W
Software Environment: Ubuntu Gutsy w/ distribution kernel (2.6.22-14)
Problem Description: All 2.6.24 and 2.6.25 kernels fail to boot properly, with
the following error looping indefinitely:
ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4)
The above correspond to my two SATA physical drives. All 2.6.22 and 2.6.23
kernels work perfectly on this same machine. Was there some type of change
starting with the 2.6.24 kernels that is rendering my PC inoperable?
I have tried looking for similar reports on this, and so far I have only found
one entry on the mailing list that deals with the same issue. The problem was
apparently solved by a BIOS flash to the latest revision, which I'm reluctant
to do since the newest BIOS from ASUS has several bugs that renders my
particular system unusable.
Steps to reproduce:
Using the 0906 BIOS revision for the M2R32-MVP motherboard and SATA drives.
I expect this regression is due to ata, rater than being caused by changes
to the underlying platform support.
If it's a regression, are there any plans on a fix? Is the issue even
known? Reason I ask is because I have been having a real hard time
getting any straight answers on this.
