No, wait, please: the panic at the end (while unmounting disks) is surely
related to a vm problem, in fact it happens while the kernel is in free(), but
I would bet that the panic at the even boots is all but a vm problem...

Sorry, I don't understand that: you mean that every IRQ will fire the same
handler?

You're too optimist :(
It still *seems* to work: this is an extract of "dmesg":
[...omissis...]

as you can see I added some printf, to understand what is happening at boot
time. I enphatized the pcicintr line, to show you that as soon as the pcic
driver powers the board on, it generates an interrupt.
If I compile without the PCIC_DEBUG and the (new) PCIC_DEBUG_UGO defines, the
kernel crashes, and the machine don't see the HD any more.
BTW, the "WARNING: / was not properly dismounted." message comes of the vm
panic, at the shutdown.

I will test the patches until I'm able to reboot without any panic (vm or PCMCIA
related), then I will send them to you.
