Subject: brcmsmac hangs machine if loaded after busmastering disabled
Reply-To:
I'm dealing with a platform with some buggy system firmware that enables
DMA on the wireless card and leaves it running even after OS handover,
triggering memory corruption. I'm working around that by disabling bus
mastering on the device in the bootloader, but that results in the
system hanging during brcmsmac init. pci_set_master() is being called in
the bcma code, so it's nothing that straghtforward. Any idea what might
be going wrong here?
