Incorrect Intel firmware file name

Same Here.... I have an email into intel to find out if having that message actually makes the driver use v1 features though, since my wireless with the 5300 is the most stable on 5GHz that I have ever had with linux... The v1 firmware, while not having as fast of speed with 40mhz fat channels, is solid on keeping the connection in this combo currently...

greg@ghost-linux:~$ find /lib/firmware/ -iname *iwl*5000* -exec ls -la {} \;
-rw-r--r-- 1 root root 353240 2009-10-14 19:54 /lib/firmware/2.6.31-14-generic/lbm-iwlwifi-5000-1.ucode
-rw-r--r-- 1 root root 345008 2009-10-17 17:55 /lib/firmware/iwlwifi-5000-1.ucode
-rw-r--r-- 1 root root 353240 2009-10-17 17:55 /lib/firmware/iwlwifi-5000-2.ucode

Confirmed. A simple rename (I used a symlink) of /lib/firmware/2.6.31-14-generic/lbm-iwlwifi-5000-1.ucode to lbm-iwlwifi-5000-2.ucode fixes the problem. I imagine this will be the same for lbm-iwlwifi-5150-1.ucode

Adding this symlink fixes things for me:

rwxrwxrwx 1 root root 34 2009-11-04 11:01 /lib/firmware/2.6.31-14-generic/lbm-iwlwifi-5000-2.ucode -> /lib/firmware/iwlwifi-5000-2.ucode

It may be co-incidence, but without the symlink I was experiencing very unstabie connections - Thinkpad R500, Karmic amd64 - whereas with it things are stable. Without the symlink I get logged:

[ 40.952984] iwlagn 0000:03:00.0: firmware: requesting lbm-iwlwifi-5000-2.ucode

I then have frequent disconnections of the wireless, accompanied by:

iwlagn 0000:03:00.0: Microcode SW error detected. Restarting 0x2000000

As well as numerous Kernel oops'es.

[Without the backports installed I, I experience frequent lockups unless I disable wireless]

This bug is about intel firmware file names. Please report your problem
as a new bug.

id like to confirm that this is an issue on the acer timeline 3810T with backports installed.

Also the fix suggested works, could we look at getting this ajusted in backports to stop the sleek boot process being interrupted?

Confirmed with 9.10 on a Dell Latitude 2100. Seems to be easy to fix.

Same problem here with a HP 4710s laptop (Intel 5100AGN) with Ubuntu Karmic 64 bits.
Normal emailing, surfing the web works okay. I also use XBMC (media center) and when streaming movie wireless from the laptop to xbox/xbmc it randomly stops the connection. Doing a dmesg | grep error gives a Microcode SW error.
Checked with dmesg | grep iwlagn also gives the 'Please use API V2' message.
Symbolic link fixed it.
While this may be a Low importance to the majority of users, it was definitely medium/high to me.
This should be fixed in backports or wherever it should, not a symbolic link.

Ok the standard firmware files on my lucid install are these:

  b1dc5068cd536a97af7e3c0090a5a632d09ab2f3 /lib/firmware/iwlwifi-5000-2.ucode
  f06ff86c8baa8616de584f8b0fff072a9aab6a44 /lib/firmware/iwlwifi-5000-1.ucode

And the lucid lbm (which is based on 2.6.33) contains this:

  b1dc5068cd536a97af7e3c0090a5a632d09ab2f3 ./firmware/iwlwifi/iwlwifi-5000-ucode-8.24.2.12/iwlwifi-5000-2.ucode

Those appear to be correctly named based on the reporters checksums. This seems to have been fixed when we stopped mangling names for LBM in lucid. Closing Fix Released for Lucid.

This is an LBM issue, so regigged this to be open for Karmic, but closed for Lucid.

karmic has seen the end of its life and is no longer receiving any updates. Marking the karmic task for this ticket as "Won't Fix".
