Alan, pĺease excuse me. I'm a newbie in reporting kernel bugs, and my
domain with english does not help at all (i'm from Argentina).
I have a netbook that gets stuck there, it means that it stop
responding at all and i have to turn off by hand, pressing the power
button. I know it gets stuck at this point because i sailed into the
kernel's code and finally i put a printk before and other after this
call; and the later is never being shown. Moreover, if i comment that
pci_write, the whole kernel startup works ok (or at least it seems
to)...
