Re: Lazily construct slab commit causes BSOD/freeze on xen 4.16

[Owen Smith <owen.smith@xxxxxxxxx>]

I've not seen BSODs in this area with XenServer drivers which are based on the same commit, though we are carrying a patch to this area.

Do you have any details about the crash (crashdumps, bugcheck IDs, etc) that could help pinpoint the problem?

Attached is the patch XenServer's tools are currently carrying.

Our project pulled in the newest master commits and have been experiencing guest freezes/BSODs on our Xen 4.16 host systems.  I rolled back commit e5db0e07f7d2de37bb8740cdaa63caecfe4fe3e1 and was able to mitigate the issue, but I was wondering if anyone else has experienced this side effect.  If not what version of xen have you been working on this development in hopes of finding the offending xen code?  Any information would be greatly appreciated.
