2.6.24 / TI PCI1510 / Oops during insertion a CompactFlash card

[Jeongdo Son]

Hi, all.

I got a OOPS message when inserting a CompactFlash card.
The PC Card controller is Texas Instrument PCI1510.

I've searched the linux-pcmcia mailing list archives, but couldn't find a clue.
I'm wondering if this is a known issue.
Also wondering yenta_socket with pata_pcmcia is stable under SuperH
architecture.
