Hi,

note the line of "IRQ sharing enabled" for serial 8250/16550, which in
full are:

HURD may have issue with his sharing?
It is interesting that the laptop has no RS232 port... where are they?
sharing because of 4 ports with 2 IRQs, 3 & 4?

It even has a Floppy!! can I use it instead of USB :) (well... the
issue is that I could not exchange it with other computers, I have
almost none with floppies....)
Here HURD does not finish boot, I get this issue seen in dmesg
com0: at atbus0The device below will clobber IRQ4 (c10512c0)
You have two devices at the same IRQ.
This won't work. Reconfigure your hardware and try again.
com0: port = 3f8, spl = 6, pic = 4
Being a laptop, I cannot fiddle with IRQ Jumpers :) Also "it can work"
since this laptpo did run Windows, FreeBSD and Linux. Is our kernel
wrong here or doesn't support some tricks other OSs have.
I checked in the BIOS if I could "disable" internal stuff, but I
can't. This computer has no RS232 port, but does have IrDA, which is
perhaps seen as COM port?
Should I boot another OS and retrieve some information that way?
