Bug#369298: Etch upgrade breaks smc-ultra driver on 2.6.15 kernel
Package: linux-image-2.6.15-1-686
Version: 2.6.15-8
This report is for Etch as of 5/28/2006.
Etch was installed on 4/15/2006. It was upgraded around 5/24/2006,
and that appears to have broken the smc-ultra driver. A number of utilities
and libraries were automatically upgraded at that time.
This is not the same bug I reported in #362056. In this new case an
IRQ is available for the ISA-PNP Ethernet board, but the interface fails to
come up for some different reason.
---------------------------------------------------------------------------
The hardware platform is a triple-homed router/firewall/server,
consisting of:
H-P Vectra VL, Pentium Pro with 128 MB RAM and 80 GB EIDE disk, IDE CD-ROM,
and floppy disk
Two 3C905B PCI UTP Ethernet boards
One SMC-Ultra ISA-PNP Combo AUI/10Base2/UTP board
One of the 3C905B boards was used to install Debian Etch, and in the
process it was configured as eth0 with DHCP. Following installation, the
Ethernet boards were configured as follows:
# /etc/modules: kernel modules to load at boot time.
#
# Edited by J. A. Carroll for ulysses.local
#
# 2006/3/20 Added smc-ultra and 3c509, with a line to force
# 3c59x to load first so that it will always be eth0
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a "#", and everything on the line after them are ignored.
ide-cd
ide-disk
ide-generic
psmouse
# Local additions for ulysses
3c59x
smc-ultra
(isapnp doesn't load the smc-ultra driver, so /etc/modules must be
edited to make it load at boot time. But /etc/modules is read before the
PCI bus is scanned, which would cause the SMC board to become eth0; that
would complicate shorewall configuration and make the SMC unavailable for
the coax subnets. So 3c59x must be placed before smc-ultra in the file.)
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
#
# Edited by J. A. Carroll for ulysses.local
# 2006/3/20 Added eth1 and eth2 stanzas
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
# Connects to the cable modem or outer firewall
auto eth0
iface eth0 inet dhcp
hwaddress ether 00:05:02:8E:4F:3A
# The inner LAN for the upstairs Macintoshes
# DHCP server provided in this interface
auto eth1
iface eth1 inet static
address 192.168.71.
netmask 255.255.255.0
# The DMZ or inner LAN for the downstairs hosts
auto eth2
iface eth2 inet static
address 192.168.136.55
netmask 255.255.255.0
(The hwaddress statement is required to spoof the MAC address of a
defunct Macintosh. All attempts to get the ISP to provision any other MAC
address have proved fruitless. For this reason, it's not practical to use
factory MAC addresses to force specific eth? names to be assigned to
specific 3C905B boards.)
These configuration files worked as expected. The first 3C905B came
up at boot and obtained a DHCP lease, the second came up with static address
192.168.71.1, and the SMC-Ultra came up as 192.168.136.55. Pings and
everything else worked properly. Various other services and hacks were
tested, but I didn't get as far as configuring a firewall.
---------------------------------------------------------------------------
About 5/24/2006 I brought the system up to date with
aptitude update
aptitude upgrade
Following that, the SMC-Ultra board wouldn't come up any more.
Investigation showed that the module didn't load correctly and get assigned
to the interface name eth2. The error messages:

Further poking through the logs shows isa-pnp detecting the SMC
board during boot, and printing log messages stating that IRQ 5 was assigned
to the board. But we don't see that reflected in /proc/interrupts after the
driver quit working.
---------------------------------------------------------------------------
To rule out hardware problems, I rebooted the machine with Sarge.
The disk is partitioned for multiple booting, with Sarge and Etch presently
installed.
It was possible to install all drivers with modprobe commands, and
bring up all interfaces with ifconfig commands. (The Sarge install doesn't
have /etc/modules and /etc/network/interfaces configured to do this at the
moment.) All interfaces sent and received pings properly.
