cold != 0 で src/sys/dev/pcmcia/wdc_pcmcia.c:wdc_pcmcia_enable() から EIO で戻って来ちゃうのか。
cold っていつ 0 になるんだっけ…。

cold が 0 になるのは src/sys/kern/subr_autoconf.c:configure() で cpu_configure() の後か。じゃあ、probe/attach 中は cold != 0 だなぁ。
/* * Do the machine-dependent portion of autoconfiguration. This * sets the configuration machinery here in motion by "finding" * the root bus. When this function returns, we expect interrupts * to be enabled. */ cpu_configure(); /* Initialize SSP. */ ssp_init(); /* * Now that we've found all the hardware, start the real time * and statistics clocks. */ initclocks(); cold = 0; /* clocks are running, we're warm now! */

前々から zaurus の dmesg を見る度に何か違和感を感じてたんだけど、wdc at pcmcia が attach されるタイミングが早過ぎね？i386 で pcic や cardbus だと cpu_configure() 後に attach されてなかったっけ？

てな訳で src/sys/arch/arm/xscale/pxa2x0_pcic.c で attach 時のカードの probe/attach 処理をイベントスレッドの先頭に移動させてあげる事で解決。
