Hi Youquan Song,

Your comment #13 is helpful to me.

I also meet source-id verification failure in other distribution.
You said "some platform or chipset have issue for this feature". Now I have a PCIe SSD card (a product of my compnay), I want to clarify the issue is platform issue or my product defect.

My product can be flashed to a AHCI SSD or a SCSI-like SSD.
When it is AHCI SSD, inbox AHCI driver is loaded, everything is OK.
When it is SCSI-like SSD, it needs to installed our driver. I saw source-id verification failure when loading driver.
The interesting thing is, if my driver doesn't use 'Message Signaled Interrupts', the problem doesn't occur.
('Message Signaled Interrupts' default is on)

My OS is RHEL 6.1 (kernel is 2.6.32-131.0.15.el6.x86_64). (Sorry here is Ubuntu forum :P)
My platform is HP ProLiant DL388 G7, two Xeon E5620, chipset is 5520 from lspci.
