We re-compiled the kernel with 'options KDB_STOP_NMI', and were able to
get a much more full analysis of what was happening on the 6-BETA5 crash.
We crashed in top again, and it does look like we may have hit a kern_proc
bug.
in the attached file type3-core.txt you can see that it hits an exception
in:
0xffffffff802b897a is in fill_kinfo_thread
(/usr/src/sys/kern/kern_proc.c:736).
731 }
732
733 kg = td->td_ksegrp;
734
735 /* things in the KSE GROUP */
736 kp->ki_estcpu = kg->kg_estcpu;
737 kp->ki_slptime = kg->kg_slptime;
738 kp->ki_pri.pri_user = kg->kg_user_pri;
739 kp->ki_pri.pri_class = kg->kg_pri_class;
740
(kgdb) frame 8
#8 0xffffffff802b897a in fill_kinfo_thread (td=0xffffff0063311260,
kp=0xffffffffb62d8510)
at /usr/src/sys/kern/kern_proc.c:733
733 kg = td->td_ksegrp;
(kgdb) p kg->kg_estcpu
Cannot access memory at address 0x173
(kgdb) p td->td_ksegrp
$1 = (struct ksegrp *) 0x0
(kgdb) p kp->ki_estcpu
$2 = 0
(kgdb) p kg
$4 = (struct ksegrp *) 0x12b
it seems that kg is an invalid pointer.
We have started our tests again without running top.
Hope you have a great vacation.
