as the comment that goes with the patch says, * The performance counter framework will initialize the LVTPC * vector as NMI. We can't disable the framework but the kernel loader * script will do 'echo 2 > /proc/sys/kernel/perf_counter_paranoid' * which hopefilly prevents any usage of hardware performance counters * and therefore triggering of NMIs.
a workaround that makes the problem hopefully unlikely to occur but isnt a guarantee that it won't. this is essentially the exact same patch the virtualbox team uses on the newer version, they've set it for 2.6.31 and greater so i've left it unchanged. i'll quickly test for 2.6.30 -- vboxdrv occasionally fails to load on karmic 2.6.30 kernels due to active nmi_watchdog https://bugs.launchpad.net/bugs/399732 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
