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.
