But I avoided using wireless for blob transfer for the reliability of the lockups, so it's a couple of months since I deliberately crashed it.. Maybe once in a while it lead to a complete system lockup, but treat this as rumble in my memories (and could be due to the other BUGs reported, also).. notebook: ACER Extensa 5220 kernels since Linux host 2.6.32.2 #4 PREEMPT Wed Dec 30 15:19:58 CET 2009 i686 and even before lspci: 04:00.0 Ethernet controller: Atheros Communications Inc.
