There is a bug in LBM - it is based on comapt-wireless 2.6.32-rc4.. Ubuntu needs to change this immediately.. Kernel oops's are common in that release across many wireless drivers.. It has been fixed in rc5.. I cannot use lbm because of it.. -- Incorrect Intel firmware file name https://bugs.launchpad.net/bugs/453064 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
