Hi Stephane,
I'm putting together a patch set for the minimal perfmon2 for POWER, as
you know. I'm currently trying to test it on the Stephen Rothwell
kernel which you've based your current patch set on, and am seeing this
crash during boot up:
Starting irqbalance: Unable to handle kernel paging request for data at
address 0x30302c3030303030
