Description MASAO TAKAHASHI 2007-02-01 02:11:02 EST
Description of problem:

Enabling ATA component makes "Buffer I/O error".
When booting, many error messages has displayed as follows.

Feb  1 13:39:37 mtakahashi kernel: attempt to access beyond end of device
Feb  1 13:39:37 mtakahashi kernel: sda: rw=0, want=78156003, limit=78125000
Feb  1 13:39:37 mtakahashi kernel: Buffer I/O error on device sda3, logical
block 76581632

But, enabling IDE component does not make the above error.
Environment:
   HDD : IDE UDMA5 60GB
Version-Release number of selected component (if applicable):
linux-2.6.19-1.2917.fc7

How reproducible:
to enable ATA component and to disable IDE component.

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:


Additional info:

The HDD has a Host Protected Area.
I formated with IDE driver.
The IDE driver disables a Host Protected Area.
So native capacity is 78165360 sectors.
And limit capacity is 78125000 sectors with a Host Protected Area enabled.

The ata_piix driver does not disable a Host Protected Area.

Test patch upstream. Need to trace down a problenm with some Macintosh boxes
before it can be merged however
Comment 3 MASAO TAKAHASHI 2007-04-17 01:07:51 EDT
I have tested linux-2.6.20-1.3079.fc7.
This is applied linux-2.6-libata-hpa.patch.
This patch disables the host protected area.
I think that the patch resolves problem.
Thank you, Mr Jones.
