PCMCIA / compact flash / au1x00

[Aeschbacher, Fabrice]

I tried with another compact flash (this time, a SanDisk). Surprisingly,
I got some other results. The card still appears or disappears in
/sys/bus/pcmcia/devices as I plug or unplug it. But now I can see some
messages on the console:

o when using ide-cs:

  pccard: PCMCIA card inserted into slot 0
  pcmcia: registering new device pcmcia0.0
  hda: SanDisk SDCFB-64, CFA DISK drive
  ide0: Disabled unable to get IRQ 35.
  ide0: failed to initialize IDE interface
  ide0: I/O resource 0x10200E-0x10200E not free.
  ide0: ports already in use, skipping probe
  ide0: I/O resource 0x10200E-0x10200E not free.

  ide0: ports already in use, skipping probe
  ide-cs: ide_register() at 0x102000 & 0x10200e, irq 35 failed

o when using pata_pcmcia:

  ata1: PATA max PIO0 cmd 0x102000 ctl 0x10200E bmdma 0x0 irq 35
  pata_pcmcia 0.0: irq 35 request failed: -89
  pata_pcmcia: probe of 0.0 failed with error -12


The same console messages are generated if I run pcmcia-socket-startup
later.
