| |
This is from our SMP machine which has been experiencing bi-weekly silent freezes with kernels all the way back to 2.0.3x. This morning I actually got an Oops. I don't know if this is related to the silent freezes or not.
I'm not subscribed to the list, so CC: me if you have any questions.
Thanks, Mark
