Tejun,
Do you want to say, we need to call above routines for both hotplugging
events: card insert and remove??
Actually i am getting following messages on insert:
ata1: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0xe frozen
ata1: soft resetting link
ata1.00: CFA: TRANSCEND, 20091215, max UDMA/66

sda:

and following messages on card remove:

For me, card insertion messages are fine, but I am not sure if card removal
messages are fine??
