On the good run, I don't get any message, which is good.

On the bad run, I got the following message ...

boston kernel: nf_ct_tcp: invalid packed ignored IN= OUT=
SRC= DST= LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=8162
DF PROTO=TCP SPT=1016 DPT=515 SEQ=3834958843 ACK=0 WINDOW=32792
RES=0x00 SYN URGP=0 OPT (0204400C0402080A0000CC190000000001030307)
UID=0 GID=65534

This message is displayed repeatedly after the job got "stuck", once
ever 3 seconds coinciding with every 3 seconds of the print job sent.

Hope this helps.
