Title:
  WIFI-toggle on rt2860sta in kernel 2.6.27-7

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This is an informational post regarding the eeepc_laptop - handling of
  wlan using the rt22860sta - module on the eee1000

  Adamm, using "echo 1/0 > /sys/class/rfkill/rfkill0/state is currently
  exhibiting the same or similar errors with pciehp that were present in
  eeepc-control 1.3.3 on hardy.

  loading pciehp with "pciehp pciehp_poll_mode=1" in /etc/modules causes
  the system to hard-crash immediately upon echoing 0 or 1 to .../state,
  just like the original acpi-scripts did on eeepc-control 1.2.x (the
  ones that were not rt2860sta-aware and did all its functions on the
  ath_pci - module)

  leaving the loading of pciehp out of /etc/modules (ie not calling it with pciehp_poll_mode, or perhaps pciehp_force) causes the machine to work, but the wireless will not properly load/unload, with the same kind of error messages:
  ...

  Nov  5 12:16:19 minimeee kernel: [ 7765.663257] ERROR!!! BBP write R81=0xffffffff fail
  ...
  etc ad nauseam

  Interacting with rt2860sta (via network-manager, like trying to switch
  AP's) while the module has been faulty unloaded like this will cause
  the machine to hard-freeze again.
