I have found several postings asking about suspend problems on IBM
thinkpads, but no answers so far. Here is what I have so far:
Using APM with ACPI and CPUfreq disabled: Suspend works, but only if
running on battery. When running on AC, I get what sound like PCMCIA
failure beeps (brief high low), the display goes dark, but the system
keeps on running and hitting any key brings be right back (at least
usually, using earlier versions of 2.6 circa .2, the system would
sometimes lock up after restoring the screen, at which point, sometimes
C-A-Del or Alt-sysreq-B would work, and sometimes not.)
FWIW: there were no problems with suspend under any 2.4 kernels.
.config is attached. Let me know if anything else would help.

I can confirm the exact same behaviour on a Thinkpad A20m.

Do you have a pcmcia card inserted? IBM Thinkpads (at least older models,
the TP600 for sure) don't suspend, if (AC && PCMCIA_CARD_INSERTED). If
only AC or only CARD_INSERTED, then they suspend.

Nopes, no pcmcia-card inserted. And, as noted by Vincent C Jones,
the 2.4-kernel manages to suspend my Thinkpad just fine,
even when (AC && PCMCIA_CARD_INSERTED).

Nope, PCMCIA and Memory card slots are empty and nothing is plugged into or
connected via IRDA or USB. Shutting down eth0 (built in Ethernet) or
eth1 (built in 802.11b) has no impact.
Just in case they are useful, attached are the syslog and dmesg
entries for A/C and battery suspend events.
Thanks for your interest!
