[PANIC] RELENG_6: Memory modified after free

[Gordon Bergling]

Hi,

sometimes I am gettings this panic while booting.

I had several times tried to get a core dump, but savecore(8) tells me

| savecore: unable to open bounds file, using 0


| Memory modified after free 0xc15fc000(4092) val=0 @ 0xc15fc000
|
|
| Fatal trap 12: page fault while in kernel mode
| cpuid = 0; apic id = 00
| fault virtual address   = 0xffff0020
| fault code              = supervisor read, page not present
| instruction pointer     = 0x20:0xc06018a7

| frame pointer           = 0x28:0xc0c2093c

|                        = DPL 0, pres 1, def32 1, gran 1
| processor eflags        = interrupt enabled, resume, IOPL = 0

| Uptime: 1s
| Automatic reboot in 15 seconds - press a key on the console to abort
