<div>Did you try increasing the stack size? When you inserted the
printk statements, were there any warnings about format strings not
matching the number of arguments? Have you tried disabling the
siblings yet?<br>
<br>
Thanks,<br>

Hello,<br>
<br>
yes increasing stack size helped with the printks. And yes I tried to
disable siblings by adding uses CONFIG_LOGICAL_PROCESSORS and default
CONFIG_LOGICAL_PROCESSORS=0 to the Options.lb file but it complains at
building time that this options is unkown so I uses LOGICAL_CPUS
instead (is it the same?) without results.<br>

Unexpected Exception: 6 @ 10:00207fbd - Halting<br>
Code: 0 eflags: 00010013<br>

<br>
Now I know that the the exception comes up in the corresponding
init(dev) for the PCI: 00:02.0 device. So I disabled PCI 2.0 in the
device tree and it just doesn't has any effect even it tells me that
PCI 2.0 enabled 0 at boot times, it stucks at the same place. <br>
