: More data: with a modem card the behavior is different: if I power
: the card off ("card removed" shows up) and then I extract it, the message
: does not appear again; but, if I inmediately insert the card, then
: it is not detected until I type "pccardc power 0 1". Something
: is broken...
I noticed something interesting when testing a 4.1.1-REL install
on an HP Omnibook 900. If I eject (or pccardc power [01] 0) the
ethernet card (Linksys EC2T using if_ed), the system sees the
event and the irq returns to the pool (or whatever the informational
message is); however, if I do the same with a modem, I do not
get the unloaded irq message (and I get a device allocation error
on the reinsert event). I also noticed if I look at 'systat -vmstat'
sio1 is still in there even if the card is ejected. I think something
goofy is going on here. I am currently running the pcic in polling
mode, but I will see if stealing irq 4 from the serial port (disabling
it in the bios) will help.
