o Better resume code. Move the comments around. Force the socket state to be querried. Ack the interrupts properly. o Intercept the interrupt requests and keep a list of interrupts to service ourselves. When the card attaches, set its OK bit. When we get a card status change interrupt for that card, clear the OK bit. Don't call the ISR if the OK bit is cleared. Iwasaki-san and yamamoto-san have both sent me patches that fix the same problem this fixes, but at the pccard level. o Try to get the signalling of the thread to actually die. This might not be 100% right, but it is less wrong than before. o Add a SIC next to a TI type that looks like it could be wrong, but isn't.
