Crash tool issue since printk re-implementation

[Sebastien Fabre <sebastien.fabre@xxxxxxxxxx>]

Hello,

Since kernel v5.0, PREEMPT_RT patches contain printk re-implementation. This re-implementation removes some log symbols in 
VMCOREINFO and crash tool cannot retrieve kernel logs (because symbols no more exist).
Is this impact on crash expected? If so, how can we retrieve a functional crash tool with kernel v5.0 (and following) ?

Thanks,
Fabre Sebastien
