Title:
  iwl3945 wireless connection becomes unreliable

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  what I expect:  wireless connectivity to be reliable and consistent
  what happens instead:  wireless connection cuts out, recovers, re-establishes connection.  sometimes (rare) requires disabling / re-enabling via hardware or software switch.   sometimes (more rare) hardware fails completely until reboot (removing and re-inserting module fails -- hardware disappears to the system until reboot).  This problem will occur without a suspend / resume cycle.

  This problem appeared recently, within the last month or two months of
  kernel updates.  I think the next step in debugging would be to test
  reliability against previous kernel versions.

  some relevant dmesg:
  keyboard: can't emulate rawmode for keycode 240
  iwl3945 0000:0c:00.0: BSM uCode verification failed at addr 0x00003800+0 (of 900), is 0xffffffff, s/b 0xf802020
  iwl3945 0000:0c:00.0: Unable to set up bootstrap uCode: -5
  iwl3945 0000:0c:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0xFFFFFFFF

  iwl3945 0000:0c:00.0: bad EEPROM signature,EEPROM_GP=0x00000007
  iwl3945 0000:0c:00.0: EEPROM not found, EEPROM_GP=0xffffffff
  iwl3945 0000:0c:00.0: Unable to init EEPROM
  iwl3945 0000:0c:00.0: PCI INT A disabled
  iwl3945: probe of 0000:0c:00.0 failed with error -2
