vga_pci: Fix cached resources cleanup and setup driver's softc sizebuild either dports or pkgsrc from scratch, then build say devel/gettext. On multiple machines there is a panic similar to:

The reason I mention m4 1.4.17 is that a recent upgrade appears to use __fpending which on DragonFly is defined contrary to how it is apparently defined in Linux, with the most serious potential problem that DragonFly's __fpending returns a signed value. The panics are not observed building perl or even building world and kernel, so it does not appear to be a general problem with the new syncer code.
dports m4 is patched to paper over the differing signatures of __fpending in order to even get m4 1.4.17 to build. I get the same panics when I applied the dports patch to pkgsrc to get its m4 1.4.17 to build.
It is possible m4 is blameless, but whatever the problem is, it seems fairly serious since it manifests in the build path of git which would enable further updates to src or dports if there is a fix ...

- Subject changed from panic building devel/gettext post update to m4 1.4.17 to panic building devel/gettext
Actually it appears that the panic building say devel/gettext may appear even before m4 1.4.17 is built.

Is there any new developments here?
I've never seen a similar panic. The m4 patch has been in place for a while without complaint as well.
Is anyone else seeing this panic?

kernel - Fix bug last commit (2)I have also observed that the systems where the problem occurs appear to have ufs as the filesystem, whereas some other systems with hammer do not exhibit the same problem.

- Priority changed from Normal to High
I believe this problem needs to be addressed before the 3.6 release because it may affect many if not all systems using the ufs filesystem.

I can confirm these panics.
I just got two of them, of of 2 attempts, on an oct 18 kernel/world (i386, UFS)
Now that I think about it, I had them before but I didn't make the connection until now.
