I'm seeing a similar problem after upgrading from 
2.6.25.14-108.fc9.x86_64 to 2.6.27-rc6.

>From what I can tell the messages
Sep 23 10:27:20 pangw kernel: ata6: EH pending after 5 tries, giving up
Sep 23 10:27:20 pangw kernel: ata6: EH complete

are printed for a disconnected ATA port that's a neighbor
of one that's occupied.

these are the ports that are in use:
Sep 23 10:19:40 pangw kernel: ata1.00: ATA-6: ST3160023A, 3.01, max UDMA/100
Sep 23 10:19:40 pangw kernel: ata2.00: ATAPI: _NEC DVD_RW ND-3550A, 1.05, max UDMA/33
[PATA]
Sep 23 10:19:40 pangw kernel: ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

The WDC drive was previously on ata3 and the message were then printed
for ata4.  This makes me thunk it might be related to managing of
dual-ported sata_nv chips?
