Description Eric Valette 2011-07-19 16:24:26 UTC

When I have atl1c module loaded along with ath9k for WiFi my acer one 522 freeze without even emitting a gasp. Removing the module before it freezes, make the netop works for hours. Unplugin the thernet cacle while on ethernet also cause the system to hang.

there are already plenty of bug reports regarding this triver which I know is experimental like <http://www.manticore-projects.com/content/en/software/guides/aspire522.htm> but also <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/512764> 

The bug seems to have appeared on many different hardware. Probably related to intr management but have no way to provide any traces as reset button for 5s is needed.

Can provide dmesg, dmidecode and so on. Just ask.

OK fine with me. BTW, the atheros guy mail address marked as MAINTAINER 
for atl1C bounce. I do not know, if its due to absorpsion by qualcom or 
if he just left.

If this is still present in modern kernels please update the bug
