I see the same problem with FedoraCore2 Test3 snapshot on my T40. Must
be a 2.6 kernel/ ACPI bug. I can get it to fail quickly (after resume)
by invoking a huge file transfer over eth0. No such issue when using
APM.

I've seen this (memory_cs) with early (FC2) beta kernels on a 600E - I
attributed it to failing hardware on the 600E (happend erratically
with the pcmcia card in Socket-0 - but worked correctly with
Socket-1).

However I haven't seen this happen on the T40. The FC2T3 kernel on the
T40 is much newer version (than the one that gave errors on the
600E). Perhaps this issue is already fixed. The current FC2-beta
kernel is 2.6.6-rc3+

I must say this happened to me with FC1 2.4 kernel. (with a simple
power cycle to reboot) I've had other issues with the FC2T3 kernel as
well. (with USB-2 external HDD)

Looks like some of these are 2.6 kernel issues with the T40 (common
across distributions) - hopefully they get fixed.
