Hello again,

As I experimented at which size of file kernel starts to produce those

Jun 24 14:56:46 jm22 kernel: 03:05: rw=0, want=1952804549, limit=3076416

messages I noticed that 100MB seems to be critical size for file in this
respect. I tested 'sum <file>' with different filesizes and with 50MB
file there was no problem but trouble started with 100MB file.
