Hi, Ryan, I came across the similar problem on 8-stable when I run
# dtrace -lv
the panic message says:
page fault just happened at fbt.c
........................................................................
if (*lc.ctfoffp == NULL) { // page fault
/*
* Initialise the CTF object and function symindx to
* byte offset array.
*/
if (fbt_ctfoff_init(ctl, &lc) != 0)
return;
/* Initialise the CTF type to byte offset array. */
if (fbt_typoff_init(&lc) != 0)
return;
}
........................................................................
And I came across the similar problem on 9-current only once, but when I
recompile the kernel,
it does not reproduce. I will try your patch on 8-stable, but could you tell
me where did you meet
the problem, and what is your module without CTF data?
