Installing an updated kernel will not hurt, you can keep the current one (Debian Squeeze stock) and compiling (or installing from backports) a new one. > I also have an ASUS laptop on which I installed Debian Squeeze on a > dual boot together with MSWIN XP.

The afore mentioned bug was present on PCI cards while not in PCI-Express based cards, maybe that's the difference. *** Hangs with PCI devices and SMP systems This issue was due to a hardware limitation on our PCI devices whereby our device's FIFO queue got filled up and caused a loop. This issue is only present on our 11n PCI devices, its not present on our PCI-express devices nor our legacy 802.11abg devices. *** > I carried a few more tests on the problematic Desktop.

The problem is on the kernel module, I can't see how user space tools such can cope with this unless getting an updated kernel/driver. > If I were to upgrade kernels, which kernel would you recommend ? I would try with the backports one, as it's easier to install. If that also fails, I would compile the latest stable kernel from sources available at kernel's site (now 3.2.9).
