A follow-up by shutting down PCMCIA and rmmod'ing all the related modules ie ide_cs, ds, yenta_socket, pcmcia_core the suspend works on AC again. So, I add them back one by one: pcmcia_core -> still works yenta_socket -> FAILS! rmmod yenta_socket -> works again! Summary: suspend works on my Thinkpad T21 (a) with no apm module or apmd but with all PCMCIA (ie. hardware suspend- close lid etc); (b) with apm & apmd and all PCMCIA but no AC power (c) with apm & apmd but no yenta_socket and the rest but with AC power The problem is a combination of apm, yenta_socket and AC power. pZa1x wrote: > I would like to join in here.
