Further to my previous entry, whilst looking through my box of computer bits looking for something else, I came across an old wifi card an RT2500. I removed my RT61 and inserted the RT2500. I now have no problems with kernel freezes with ACPI on or off.
I am convinced that this is a bug in the RT61 driver. -- Packard Bell EasyNote MZ35 freezes when AC unplugged and wireless on https://bugs.launchpad.net/bugs/666852 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
