Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I have a wireless network card that is supported by the kernel's prism54
driver (I have never needed to use ndiswrapper). It worked flawlessly
under Breezy until I did a dist-upgrade to Dapper last night.

Note: my symptoms look something like those in the comments of 31502,
but I'm not sure if this is the same problem.

* On boot, the wireless card's lights did not come on.

* I made sure the prism54 module was loaded; it was.

* I checked lspci; there was an entry for the card.

* I checked iftab; the card's MAC address was matched with "eth1". One
other entry existed, for my wired interface.

* I ran `ifconfig -a`. eth0 (my wired ethernet port) was listed. There
was no entry for eth1 (!) and there was a strange entry for 'eth2', with
a MAC address that does not exist on any of my system's network
hardware. No IP assigned for the mysterious eth2, of course.

* I tried restarting networking using `invoke-rc.d networking restart`. I got the following output:
=====
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device eth1 ; No such device.
SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
eth1: ERROR while getting interface flags: No such device
Failed to bring up eth1.
=====

* I tried unloading, then loading the prism54 kernel module. No lights,
and no change to any of the above.

* I removed and inserted the card. I got the following output:
=====
[4294853.938000] Loaded prism54 driver, version 1.2
[4294856.944000] pccard: CardBus card inserted into slot 0

[4295095.000000] ACPI: PCI Interrupt 0000:02:01.0[A] -> Link [LNKB] -> GSI 10 (level, low) -> IRQ 10
=====

I'm at a loss; I can't seem to make the system see the card as a network
interface, or even get the card to show a light, even though it worked
flawlessly under Breezy. One other thing - under Breezy, dmesg showed
card firmware being uploaded - that does not appear to be happening in
Dapper.

kernel package is 2.6.15-17-686.
