Hi,
I already asked this about week ago... But today I was informed
that jimbud@arborlink.com received oopses below too. It really looks
like that vmmon does something wrong, but I cannot find anything.
Does anybody here have any idea how could happen that there is
page which has page->mapping == NULL, but filemap_write_page is
called on that page? It happens when VMware exits...
FYI, it did not happen with 2.4.0-test8-pre1 (yet?) and I'm not
sure whether I trust -pre6 enough to upgrade.
Thanks,
Petr Vandrovec

When VMware runs here, it has mmaped following things into memory. But
absolute addresses may differ between oopses above and log below.
