The problem persists in both cases, but there are subtle differences...

With CONFIG_BLK_DEV_IDE_TCQ_FULL it will lock regularly.
The auto fsck at boot is good at killing it; it locked up at 51% last time.
Occasionally it will make it as far as PostgreSQL and nfslock startup,
but no further.

With !CONFIG_BLK_DEV_IDE_TCQ_FULL it survives fsck
regularly. However, it still locks up around nfslock and PostgreSQL
startup. Interestingly, if I disable those two items, it boots every
time and (even more interestingly) I can start both by hand after
boot and it "seems" stable.

Your wish is my command...

P.S. The following messages in reference to the CDROM are now emitted
during device detection. I assume it's because I have no media in the drive,
but since this is new behavior with the patch you sent I figured I'd note it.

hdd: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hdd: request sense failure: error=0x24
hdd: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hdd: request sense failure: error=0x24
hdd: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hdd: request sense failure: error=0x24
