Maybe the soft lockup report is cause by the clock change (it doesn't show any kmemleak functions in the backtrace). You could change SCAN_BLOCK_SIZE in memleak.c to a smaller value as the scanning is done with the interrupt disabled. I'll try tomorrow on my platforms with the soft lockup enabled. -- Catalin
