This server was just upgraded from 2.2.6-RELEASE to 2.2.7-RELEASE (including a newly built kernel based chiefly on GENERIC), and ever since it exhibits these intermittent panics: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x18 fault code = supervisor write, page not present instruction pointer = 0x8:0xf011e3d1 stack pointer = 0x10:0xefbffe9c frame pointer = 0x10:0xefbffec0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume , IOPL = 0 current process = 501 (pnserver) interrupt mask = panic: page fault The panics seem to occur during periods of high activity after running for a couple of hours. Otherwise, it appears to operate fine. Prior to the Intel card, it was running an SMC Rev C (de driver) card that was even more sensitive and paniced frequently. I'm considering reverting back to 2.2.6 unless there is a known issue with 2.2.7-RELEASE that has been resolved in -stable. Or maybe there is no some new kernel tweaks required in 2.2.7 to avoid this? Any assistance is much appreciated. Thanks.
