Thank you Frank.
I think that the heavy disk i/o could be the cause, but please consider
this:
1) I could reproduce the hang only via wifi network, using the intel wifi
card (802.11g).
2) using the gigabit ethernet connection i haven't got the problem.
3) during the test of the sd-at-atapi kernel mod, I have managed to send
and receive between my internal disk and the usb disk a burst of 5Mb files
and my beloved :) 20Gb file, repeatedly:
no hangs at all. Maybe the long duration of the wireless file transfert
could affect this issue?
May I ask you how I can activate the kernel/device driver debugger? I tried
to recompile the kernel with debug option enabled, and defined also
iwi_debug in source driver, but I'm only able to obtain messages during the
ifconfig/wpa supplicant phase.
In driver source there's a NDBGL? macro: how can I enable and use it???
Google doesn't help in this case! :)
Now i'll leave my dsm box under heavy disk load via gigabit ethernet all
night long, hope I could reproduce the same problem.
Bye!
