Having problems sending the MIME encoded. Let me just retype in plain text: ------------------------------------------------------------------- Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 00 fault virtual address = 0x50006 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff805276a7 stack pointer = 0x28:0xffffff81d8190750 frame pointer = 0x28:0xffffff81d81907a0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 7601 (ls) trap number = 12 panic: page fault cpuid = 1 --------------------------------------------------------------------- Additional information since the submission of the bug report: The original netboot/system build was done on disks that had FreeBSD file systems from an earlier release of FreeBSD. During the system installation process, the disk slices and partitions were not redefined but were reused. The file systems on them were remade. Since then, I have found that if, during the installation process, I delete all the slices (and partitions) and create new slices and partitions, I don't seem to be having the problem. I've only done limited testing with this procedure. This presents a problem for us. We need a way of not losing the data that is on the FreeBSD slices that are not affected by the sysinstall (i.e. all the data that are on user only partitions and in the PostgreSQL database). Is there a way of doing this, or do we have to reslice and repartition all the disks. Thank you for any help that you can provide. Henry Wong
