Now I have a "sleep 7" script before and after /etc/rc2.d/gdm and that works.
When I look through the syslogs, the exception always happen between
[ 90.066878] tg3 0000:06:06.0: firmware: requesting tigon/tg3_tso5.bin
and
[ 128.062549] tg3 0000:06:06.0: wake-up capability disabled by ACPI
[ 128.062558] tg3 0000:06:06.0: PME# disabled
so I suspected it was something like in bug 331415. However, it also happens when I blacklist tg3.
