I also can confirm this problem. A Ralink pci card 00:09.0 Network controller: RaLink RT2561/RT61 802.11g PCI
is driven by the rt61 driver. I have a 32bit single core system, so I don't think that the problem is SMP related. Same problems here: The system freezes completly from one second to another, sometimes after a few seconds, sometimes after some hours. Like Frode Solheim I also got the message soft lockup on cpu#0 as the system freezed without X loaded. -- [rt61] Lockups running Feisty on x86-64 https://launchpad.net/bugs/90243 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
