Hi David,

It turns out that a combination of the "PNP OS" setting (must be NO) in the BIOS and the "exclude irq" settings in the /etc/pcmcia/config.opts file were the culprets. Here is my final discoveries -- thaks to Jeremy at Sony engineering (friends in low places....) for pointers:

Make sure that /etc/sysconfig/pcmcia is set to include the following:

  • PCMCIA=no
  • PCIC_OPTS="irq_list=10,11 has_ring=0"

And add the folloing to /etc/pcmcia/config.opts:

  • exclude irq 5
  • exclude irq 7
  • exclude irq 9

Unfortunately, cardmgr doesn't seem to work if you just pop cards, but by simply stopping pcmcia, swap cards, and starting pcmcia, all is well.

As an additional note - the commercial OSS drivers support the Yamaha sound chip, but (again) are effected by the "PNP OS" setting in the BIOS -- make sure that it is set to NO!

Very Happy VAIO 505VE user.
