Suggest a bigger bdl_pos_adj. Also, sometimes the iwlagn process just hogs the CPU. When I reload the iwlagn module, it'll be fine for some time until it hogs the CPU again. So I guess the bug can be closed as it's not the very same issue anymore. But then again, I don't know how valueable this information is for you. -- Kernel crashes after resuming from Suspend (Intel Wireless LAN 3945 issue?) https://bugs.launchpad.net/bugs/309604 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
