This is becoming quite a common complaint with Sony hardware since the "pcic" device was changed to use polling mode by default. The problem is that the pccard controller seems to generate interrupts even when it has been told not to (but only when PnP OS is "no"). When an interrupt is generated, the machine gets stuck in a loop because none of the interrupt handlers for that interrupt line know how to disable source of the signal. The workaround is to specify a non-zero IRQ for the pcic device in your kernel config. e.g. device pcic0 at isa? irq 5 port 0x3e0 iomem 0xd0000 (you can do this also via /boot/kernel.conf or the UserConfig prompt with the command "irq pcic0 5"). Then change the BIOS PnP OS setting to "no", and both USB and pccard should work together.
