First you indicate in the subject that there is a regression in 6.16.3 (implying from 6.16.2 then), and you describe a 6.15.x to 6.16.x upgrade, which then has nothing to do with 6.16.x alone but much more likely with 6.15 to 6.16. Or did a previous 6.16 work fine ? Also the patch you pointed above is neither in 6.15 nor in 6.16, so it's not just "missing from 6.16". Based on your links and descriptions above I suspect that instead it's a 6.15 to 6.16 regression that was brought by a0285236ab93 and that commit e67a0bc3ed4fd above fixed it in 6.17-rc2, is that it ? If so, can you apply that patch to confirm that it works and is desired in 6.16.x ? Regards, Willy
