I got the list of modules down to: Module Size Used by ipv6 254836 14 ext3 130568 1 jbd 53908 1 ext3 mbcache 16004 1 ext3 loop 22540 2 sd_mod 41240 2 crc_t10dif 10112 1 sd_mod ahci 37260 1 libata 176160 1 ahci scsi_mod 156948 2 sd_mod,libata processor 49708 2 fuse 58780 3 and that still failed the second resume. Just to remind you, the first suspend/resume (echo mem >/sys/power/state) works, but the screen is black on returning from the resume. I can then (blindly typing) do a second suspend but resume still hangs the machine. b.
