Thank you for replying. Yes, I meant the tg3 driver. I reinstalled it
by reinstalling the package firmware-linux-nonfree using apt-get. Then
I began to reinvestigate the matter. I now think the problem is related
to the iwl3945 driver, which is part of the package firmware-iwlwifi.
The relevant output for “lspci -vnn” is the following:

(I removed the serial number for the wireless card. Was I supposed to
remove anything else?)
I reinvestigated the matter by suspending the laptop to RAM several
times, to disk several times, and intermixing the two. Suspending to
RAM a single time and then following by suspending to RAM or disk
creates the problem. (By suspending to RAM I mean clicking on the K in
the bottom, left corner of the screen, clicking on “Leave,” and clicking
on “Sleep, Suspend to RAM.” For suspending to disk I mean clicking on
“Hibernate, Suspend to disk.”)
Again, The first attempt to suspend to RAM will succeed. For the next
attempt, whether I try to suspend to RAM or disk, it will fail.
Otherwise, the laptop will suspend to disk successfully twice in a row.
In the failing cases for RAM and disk the relevant output in the system
log is the following:

Both cases produce the same error messages:
kernel [ ] legacy_suspend(): pnp_bus_suspend+0x0/0x6f returns 38
kernel [ ] PM: Device 00:0c failed to freeze: error 38
What is error 38? Does 00:c refer to the wireless card? If so, perhaps
the bug should be reclassified under the package firmware-iwlwifi.
Thanks, Ryan.
P.S. It seems the encrypted file system is irrelevant.
