current as of 2004.07.25 01:20
on the serial console, i get
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x10
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc04df9dc
stack pointer = 0x10:0xdf0c4ae0
frame pointer = 0x10:0xdf0c4b00
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 50966 (mysqld)
but the real pain and question is that it does not fall into
kdb. and hence i had to get remote hands to go into colo and hit
the reset. this costs money!
kernel is built as
options KDB # Enable kernel debugger support.
options DDB # Support DDB.
options GDB # Support remote GDB.
what am i doing wrongly?
