I think I am going through similar issues curently, with my TBS6280 card.
It randomly disappeared from my system, in that lspci showed nothing at
all, even after several reboots.  Worked OK in another PC, so thinking I
have a dodgey motherboard, so will be replacing soon (hardware
recommendation post coming soon....).

My problem may be worse than yours, but worth checking the card is being
picked up at all with lcpci, sorry if you have already done so!

Cheers
