Subject: Badness in map_area_pte
Date: Sat, 15 Jan 2005 19:08:50 +0000	[thread overview]
Message-ID: <41E96A42.7090501@mc.net> (raw)

Badness in map_area_pte at mm/vmalloc.c:126
[f0062a8c : map_area_pud+0x50/0xac ] [f0062c20 : map_vm_area+0x94/0xd0 ] 
[f00631bc : __vmalloc+0xe0/0x134 ] [f0048124 : load_module+0x38/0x9dc ]

I am getting multiple stack dumps like this one when I do a "modprobe nfs" 
with kernel 2.6.11-rc1 on my SS20.  This only happens when I use the 
framebuffer console (cg14), and when it happens the top part of the display 
gets corrupted.

Here is line 126 of vmalloc.c:
   WARN_ON(!pte_none(*pte));

At this point, I am guessing that some pte's allocated for the framebuffer 
are being wrongly re-used when loading the module.

Bob
