[1.] One line summary of the problem:
System freezes when changing MAC address
[2.] Full description of the problem/report:
When I try to change the MAC address of my Broadcom BCM4401-B0
ethernet card without having activated the network interface
first, my system freezes. There is no kernel oops or panic.
I am using a Samsung X20 XVM 1730 V laptop running Ubuntu 5.10,
my kernel version is 2.6.12-10-686.
When I activate the interface first ("ifconfig eth0 up"),
deactivate if again ("ifconfig eth0 down"), and then change the
MAC address, the problem does not occur, even if I remove and
re-insert the b44 kernel module in between.
[3.] Keywords (i.e., modules, networking, kernel):
networking, b44
[4.] Kernel version (from /proc/version):
Linux version 2.6.12-10-686 ([EMAIL PROTECTED]) (gcc version 3.4.5
20050809 (prerelease) (Ubuntu 3.4.4-6ubuntu8.1)) #1 Sat Mar 11 16:22:51
UTC 2006
[5.] Output of Oops.. message (if applicable)
n/a
[6.] A small shell script or example program which triggers the
problem (if possible)
1. Boot the system with boot parameters "ro" and
"init=/bin/sh" (parameters are not necessary to
reproduce the problem, as long as the interface
is not automatically brought up during the boot
sequence).
2. Issue the following command:
"ifconfig eth0 hw ether 00:11:22:33:44:55"

(Please let me know what other information could be helpful.)
[X.] Other notes, patches, fixes, workarounds:
Inserting a lot of "printk"s into b44.c (I'm a newbie), I found out the
following:
- b44_set_mac_addr() gets called (as it should).
- __b44_set_mac_addr() gets called.
- __b44_cam_write() gets called.
- b44_wait_bit() gets called.
- The freeze seems to occur upon calling br32().
- The four calls to bw32() encountered before (one in
__b44_set_mac_addr(), three in __b44_set_mac_addr()) do not
produce a freeze.
- The parameters to the critical call to br32() are the following:
bp = 0xdfb8d220
reg = 0x428 (= B44_CAM_CTRL)
[bp->regs = 0xf9080000]
