Bug Description
The Broadcom 4311/12 wireless chips require firmware when using the b43 driver.
This firmware is available from Broadcom (which is put into /lib/firmware/b43)
or as open source (which is put into /lib/firmware/
works, but when the proprietary Broadcom firmware is not present in .../b43,
shutdown takes an extra minute, after the log file line "could not find
.../b43/ucode5.fw". After a minute, shutdown completes normally.
Adding in the Broadcom firmware lets shutdown proceed without the minute
delay. This behavior is new with the 11.10 release.
Note the below udev items from /var/log/udev are probably the cause of this
problem.
...
KERNEL[18.445953] remove /devices/
UDEV_LOG=3
ACTION=remove
DEVPATH=
SUBSYSTEM=firmware

ASYNC=0
SEQNUM=1822
.....
and many other FIRMWARE=b43/...fw paragraphs
The open source firmware is available in packages firmware- b43-installer and firmware- b43-lpphy- installer. It is not certain that the system with the problem had used those packages, however. The firmware may have been compiled directly, or copied from another system.
