Hello there,
I have a Dell 1655MC blade server. It's a chassis of 6 PCs in a 3U case. Each
blade has two Broadcom BCM5703 interfaces. Unfortunately, its behaviour is
rather non-deterministic. The chassis allows one to access the serial port of
each blade. By default, the console is redirected out of there, but by
switching that off one might be able to use the serial port for gdb, if one
can get past the chassis and typing "connect server-1" part of the Dell ERA. Hrm.
The dmesg output follows. As you see, there are two bge0s (!) and neither has
an associated PHY. It's not always like this, however. Sometimes it boots
fine, both interfaces are detected OK and one can proceed to do an NFS install
of the minimal distribution set. Once the interface has been configured, it
seems to be stable.
Sometimes, the kernel panics when one uses ifconfig(1) It panics in
bge_stop+0x283 , which from the disassembly (remember I haven't been able to use
gdb remote debugging yet) is this address:
3454: 8b 45 f8 mov 0xfffffff8(%ebp),%eax
>> 3457: 8b 70 08 mov 0x8(%eax),%esi
345a: 8b 7e 08 mov 0x8(%esi),%edi
This appears to be in the bit where it brings the PHY down, but leaves
the media type unchanged. (lines 2801 -> 2810 of sys/dev/bge/if_bge.c)
Here's a backtrace. The reader is also referred to PR i386/46484
