Now, of course, it's not the staging-next kernel (I'll try that now this doesn't work) but perhaps this report will still be of use to the Broadcom/other wireless folks. After loading the module, the system hangs soon thereafter and does not respond to any sysrq. I tried setting panic_on_oops and configuring kdump but I can't get the system to panic in any case, and setting pause_on_oops doesn't give me enough output, either. So the best I have at this time of night is the output from a netconsole, which actually seems to work well enough (I don't see any further output on the console itself). This is happening on a brand new ASUS Eee PC 1015PEM netbook, which contains the following Broadcom part: 02:00.0 0280: 14e4:4727 (rev 01) Subsystem: 1a3b:2047 Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fbffc000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information: Len=78 Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number XX-XX-XX-XX-XX-XX-XX-XX Capabilities: [16c] Power Budgeting Kernel modules: brcm80211 The firmware files have been installed correctly also. I will poke some more, trying a pure upstream Linus tree and next-staging next, and I am happy to try patches sent to me and let folks know what happens.
