The errors normally appear in dmesg as soon as there is any disk activity
while the card is active - it seems you don't have this problem.
That's annoying; I was rather hoping it was going to be triggered by every
SATA driver, as this would no doubt have made it easier for the devs to track
down the problem...
So far the issue has been reported on systems with sata_nv and sata_sil. I
don't suppose anyone else has either of those SATA chipsets and a bt878-based
card? It would be helpful to know if the problem is always triggered by this
combination, or whether there is something else going on.
