Routerboard 433AH - chained pci bridges problem

Reported by: Erik Inge Bolsø <knan-openwrt@…> Owned by: juhosg
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: ar71xx Cc:

Description

I have a mildly "interesting" setup here with one pci bridge connected to another. This works fine on a via eden mini-itx board, but booting hangs in the middle of pci scanning on the ar71xx Routerboard 433AH. Would appreciate some help debugging this.

Using openwrt trunk-as-of-saturday-2010-02-20.

Boot log up to hang:
