Subject: PROBLEM: brcm80211 hangs on 2.6.36-0.34.rc6.git3.fc15.x86_64
Folks,
I tried building the new brcm80211 driver from staging-next on Fedora rawhide
kernel 2.6.36-0.34.rc6.git3.fc15.x86_64. 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.
Jon.
