https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260406 --- Comment #40 from Kristof Provost <kp@freebsd.org> --- (In reply to tech-lists from comment #39) Yes please. Let's see if that makes a difference or not. While we're at it, it'd be useful for someone who has an affected amd64 machine to try this dtrace script: #!/usr/sbin/dtrace -s BEGIN { self->in_call = 0; } fbt:pf:pfr_create_kentry:entry { self->in_call = 1; printf("In"); } fbt:pf:pfr_create_kentry:return { self->in_call = 0; printf("=> %x (@%x)\n", arg1, arg0); } fbt:pf:pfr_create_kentry:return / arg1 == 0 / { stack(); } fbt:kernel:uma_zalloc_arg:return / self->in_call == 1 / { printf("=> %x (@%x)", arg1, arg0); } fbt:kernel:cache_alloc_retry:entry / self->in_call == 1 / { printf("=> %x (@%x)", arg1, arg0); } fbt:kernel:cache_alloc:entry / self->in_call == 1 / { printf("=> %x (@%x)", arg1, arg0); } fbt:kernel:zone_alloc_item:entry / self->in_call == 1 / { printf("=> %x (@%x)", arg1, arg0); } fbt:kernel:uma_small_alloc:return / self->in_call == 1 / { printf("=> %x (@%x)", arg1, arg0); } Once the problem occurs there should be output like 'pfr_create_kentry:return => 0 (@120)'. Please attach the full log, because there's going to be more information (hopefully!) in there. -- You are receiving this mail because: You are the assignee for the bug.help
