If I remove "device pmtimer" from my config, I get a consistent panic, or variation of: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0135b0a7 stack pointer = 0x10:0xd68f2c48 frame pointer = 0x10:0xd68f2c64 code segment = base 0x0 limit 0xffff, type 0x1b processor eflags = interrupt enabled, resume, IOPL=0 current process = 12 (swi7: tty:sio clock) trap number = 12 panic page fault ... This is with leaving my USB 2.0 drive turned on during boot time. If I use the same kernel (sans pmtimer) , but boot with my USB drive turned off, all is well. Or, I can put pmtimer back in the kernel and boot with the drive turned on, but sooner or later I'll get some type of panic. Some kind of timimg issue?. I think all of these panics have something to do with leaving the USB drive on at boot time. It seems like I don't have any issues if it stays turned off. That's probably why we're not seeing any reports, I doubt a lot of folks are using a USB 2.0 HD along with ehci... Again, all this started shortly after July 14th. The USB DMA changes may have something to do with this... -- ============================================================= = Bryan D.
