I have verified that I have the correct firmware (the size is 16014 bytes and the MD5 signature matches the one posted in various forums as correct). The kernel tries to load it, but after about 20 seconds, a message indicating that it was not available appears in my kernel log. No other reason is given. As the problem occurs on a x86-64-bit system, is there a problem with loading firmware into the device on those systems? Or might I have a buggy network device?
