Sad no data flows following suspend on Vaio PCG-N505VE

On my Sony VAIO PCG-N505VE, PCMCIA works fine until the machine is suspended. Upon resume everything seems fine, but no data flows. Cards are sensed properly, the network is set up, the power lights come on. Then no data actually flows. This occurs with all cards I've trie, both pcmcia and cardbus, and with all versions of the drivers up to 3.1.5. The one exception was a modem card, which almost worked after the resume, but at an extraordinarily low data rate, eg a minute to echo each character.

With a cardbus Linksys 10/100 ethernet card, this message appears in this no-data-flowing state:

  eth0: Tx hung, 11 vs. 0.

The only cure seems to be a reboot - unloading a reloading the pcmcia subsystem doesn't help.

Some probably irrelevant information:
