It probably is supposed to be unique. In the early days it was just the irq number (which is unique), and then later the named entries were added. There's no formal spec for the format, and it's really intended to be human readable, so who can say for sure. But yeah I think it's reasonable to call it a powerpc kernel bug. Having said that, it's been like that on powerpc since 2013, so although we can fix it now, there's 12 years of kernels out there that have the duplicate entries. cheers
