Here's the output of running that vmpageinfo program. =20 This is from the first core I posted the backtrace to in the original PR: % cat vmpageinfo-25.out=20 Script started on Mon Nov 15 14:22:37 2004 vm_page_buckets[262139] ((struct vm_page *)0xc0fddd40) page not found in bu= cket list vm_page_buckets[262137] ((struct vm_page *)0xc0fe0248) page not found in bu= cket list vm_page_buckets[262139] ((struct vm_page *)0xc1214e24) page not found in bu= cket list vm_page_buckets[262137] ((struct vm_page *)0xc121d59c) page not found in bu= cket list page 131042 kvm_read: Unknown error: 0 Script done on Mon Nov 15 14:25:21 2004 And this is from the core I generated at the weekend -- ie with the vm_page.c patch applied: % cat vmpageinfo-30.out Script started on Mon Nov 15 14:26:05 2004 kvm_read: Unknown error: 0 Script done on Mon Nov 15 14:26:39 2004 At least, that's what's left displayed on the screen at the end. If you want the full output including all of the animated counters, it's at: http://www.infracaninophile.co.uk/vmpageinfo-25.out http://www.infracaninophile.co.uk/vmpageinfo-30.out I'll try and get the INVARIANTS and INVARIANT_SUPPORT stuff into a kernel ASAP -- but probably not before next weekend though.
