WARNING: at drivers/ata/libata-core.c:5090 ata_qc_issue+0x105/0x2f3 [libata](), kernel 2.6.30.4

[Krzysztof Adamski]

I'm not sure if this the right place to post this stack trace, if there is
a better place, please let me know.

I was doing an rsync when I got this trace.
This is in a 2.6.30.4 self compiled 64 bit kernel, running on a Phenon
945, the file system is XFS on a RAID5 MD array.
