Re: buildworld panics with yesterday's kernel ...
:With kern.mmxopt=0, my buildworld's are failing with
:'internal compiler error' at random times, and on a
:couple of occasions my system has panicked. Here are
:the gdb backtraces on the vmcores -
:First one (kernel not built for debugging)
Andrew, you are getting the 'vm_page_alloc: free/cache page %p was dirty'
panic. This is what was happening after my initial FP code commit.
Note that this is a very dangerous panic to get, you risk filesystem
corruption! I recommend that you drop back to a more reliable
kernel before proceeding.
What is the build date on your kernel and also make sure your source
tree is up-to-date!
Even so, the are likely still issues with the FP code in the current
up-to-date source tree, which I've been tracking down with the help
of David Rhodus. But the current failure condition tends to be a
very specific 'npxdna' panic. I hope to commit a fix soon.
