Actually, _THIS_ particular panic is quite likely fuse, you're right.

But this is one, of many, on this particular machine (but the only one
since I cleaned out several of those crashes)... The box has been
nothing-but-problematic since it got installed with RELENG_8 (the box
used to run VMWare ESX 4i and 3.5i before that with no issues). In the
past week it had some 10 panics. (but due to me being a tad hasty during
install, those panics got tossed out the window. See my other "small
default root fs" thread).

All of the panics have the following in common: Heavy IO activity. Be
that net, or disk-related. The box is backed by a megaraid 8308ELP
handling 8 sata disks, and push its io through the onboard NFE and an
addin EM.

One of those panics happened during a stresstest using buildworld, but
that may have been disk-io related.
