AW: Pcmcia: 16 bit card does not work in 2.6.18+ kernel

Tue Jul 28 10:03:05 EDT 2009

Hello Tony, 

Thx for the hint.
Startup by hand did not improve the result.

But:

Under kernel 2.6.18 the "cbdumb" shows, that "Card control" is 0x00. With kernel 2.6.9 on the same machine the value is 0x01 and it works.
The data manual of the PCI1420 describes:
Interrupt flag. Bit 0 is the interrupt flag for 16-bit I/O PC Cards and for CardBus cards. Bit 0 is set when a
functional interrupt is signaled from a PC Card interface and is socket dependent (that is, not global). Write
back a 1 to clear this bit.
              0 = No PC Card functional interrupt detected (default).
              1 = PC Card functional interrupt detected.
So it seams the there is a problem with the IRQ. 
Can anybody confirm this estimation?
And how can I make it run?

Any idea, how to set "Card Control" to "1".

Slackware has a similar looking problem in that pcmcia-socket-startup is installed in the wrong place. Try executing pcmcia-socket-startup by hand.
