One additional suggestion: Rerun all already generated reproducer tests on, 
say, each updated kernel (e.g. newer rc or even full new version). If an issue 
is detected again, send a reply to the original message to indicate that the 
issue is still there. Note, I sometimes even fear that a patch that ought to 
fix the reported issue may not completely fix it considering races.

The problem with the current approach (at least to me) is that on mailing 
lists with some volume, such reports get easily buried.

Ciao
