Hi,
With the latest trunk as well as 14.07 branch I can't get my Laguna GW2388
detect any PCI devices. Dmesg shows the following messages:
{{{
[ 49.900000] PCI: enabling device 0000:02:0f.0 (0340 -> 0342)
[ 49.900000] ath9k 0000:02:0f.0: request_irq failed
[ 49.910000] ath9k: probe of 0000:02:0f.0 failed with error -22
}}}
With versions prior to 42400, such as the BB RC3 or 42297 which is
provided by Gateworks' repository with their patches, this problem doesn't
happen. I think that it is related with the changeset 42400 to support PCI
isolated interrupts on newer Laguna boards.
I analized this changeset and I noted that the upstreamed patch has some
changes compared with the one developed by Gateworks
([http://trac.gateworks.com/changeset/553]) which probably causing this
problem since my Laguna is prior to revision 7 so, it doesn't support
isolated interrupts.
Thanks.
