PANIC: vm_page_fault: unhandled page fault in kernel space when installing packages

[jmairboeck]

I got this KDL when installing local packages and uninstalling some at the same time using pkgman in Terminal:

hrev58485, x86_64 in VirtualBox

[jmairboeck]

The same KDL happens when trying to install the package via HaikuDepot. The KDL also happened in a Terminal window thread. The Terminal was idling this time, but with /boot/system/data/texlive/texmf-dist as working directory, which belongs to the package to be upgraded.

[jmairboeck]

Upgrading the package via HaikuDepot without having a Terminal open succeeded.

[jmairboeck]

The same KDL (crash in Terminal window thread when uninstalling a package) also happens on hrev58477, so it is not a very recent regression.

[jmairboeck]

I "bisected" it as far as I could with my local states: hrev58159 crashes, hrev58095 doesn't.

[jmairboeck]

I narrowed it down further with the available hrevs: hrev58124 crashes, hrev58121 doesn't. The two between those aren't available.

I guess hrev58123~1 is the most likely culprit.
