Hello,

"Jerry" contacted me off-list with information about the root of the
problem - many thanks indeed!!!

It turns out that the e100 driver is responsible. (The motherboard actually
has a r8169 chip, but I added an old Intel PCI ethernet card I own.)

By rmmoding e100 before s2disk, the problem goes away. Jerry mentions that
he once saw a message about e100 failing to load its microcode - I never
saw such a message.

The most recent e100 commit ac7c992 by Thadeu Lima de Souza Cascardo (Apr
28) made some changes to the behaviour in the case of shutdown vs. suspend,
maybe the problem is there? (But note that during bisecting, I tested
kernels older than that commit, and not all of them worked.) Before that,
f902283 (Mar 3 2008) mentions suspend in the log message.

Cheers,

Richard
