Wake from Deep Sleep issue with Sonnet ATA133 version 4.0 drivers

Several readers are experiencing a wake-from-deep-sleep issue with Sonnet's ATA133 version 4.0 drivers with the Sonnet Tempo Trio ATA133 PCI card.

Sonnet's Firmware v3.2.5 with the PCI Tempo Trio card had a known issue waking from deep sleep in Mac OS X 10.2.3 and earlier. Mac OS X 10.2.4, 10.2.5, and 10.2.6 fixed this problem.

However, users report that after upgrading the Sonnet Tempo Trio ATA 133 PCI card with the "tempo133_firm_40" firmware updater from v3.2.5 to v4.0, under Mac OS X 10.2.6, the inability to wake from deep sleep re-occurs. A hard restart is required in order to regain system functionality,

Downgrading to the Sonnet 3.2.5 firmware will again allow normal sleep.
