Hi all

I have a problem with my Intel SR1550 server (S5000PAL motheboard, 
SATA/SAS controller, 5 SATA HDD Seagate ST9120822AS ).
The four drivers are in two md raid1, which striping by lvm and one 
drive used separately. I have problem like below with two different 
drives (ata3 or ata4) and ata5. I look problem like this with RedHat  
2.6.18-53 kernel, 2.6.24-rc8, and today 2.6.24-git5. I reading about any 
problems like this in lkml.org. There can be this message will help to 
fix this issue.
The complete dmesg in attachment.
