Could you please be more specific on which lines need to be commented out? Looking at the previous error, I tried commenting out line 1236 in function 'kcdrwd' which contains an if statement with 'PF_IOTHREAD' in it and the resulting pktcdvd.c becomes like this:

			VPRINTK("kcdrwd: sleeping\n");
			residue = schedule_timeout(min_sleep_time);
			VPRINTK("kcdrwd: wake up\n");

			/* make swsusp happy with our thread */
#			if (current->flags & PF_FREEZE)
#				refrigerator(PF_IOTHREAD);
#
			list_for_each_entry(pkt, &pd->cdrw.pkt_active_list, list) {
				if (!pkt->sleep_time)
					continue;
				pkt->sleep_time -= min_sleep_time - residue;
				if (pkt->sleep_time <= 0) {
					pkt->sleep_time = 0;
					atomic_inc(&pkt->run_sm);
				}
			}

Upon executing 'make' again still produces the following error:
make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.

So it looks worse. I am looking forward to your further help here. Thanks.
