KDL: NULL dereference in x86VMTranslationMapPAE::UnmapArea

[dsuden]

Got this screen shot from a customer who says he walked in and the system was KDL'ed. The only thing known to be going on was playback of music at the time, other than that, Haiku was just idling away. Version on his system is probably something like HR46104. Some references in the KDL message to VMA, not sure whether that's where the problem is, or indeed, as a neophyte, what that quite means. :-) Attached FWIW.

KDL

Reminds me of #8345, except #8345 is about Map() hitting a panic(), whereas this one is about UnmapArea() hitting a page fault.

It seems there was a script looping and calling "sleep".

@Dane: please check if that customer is running our "MakeMusic.sh" script, and disable it if needed.

Hat tip to you korli, I had missed that. A few weeks back we had a report of a KDL with "query" command which (unlike here) immediately ringed a bell for me; I had suggested disabling MakeMusic.sh for that other customer and never heard trouble from them again.

Ping again: is this one still reproducible?

Closing this one, haven't seen it in a long time.
