PS3 restart crash, SCSI cache sync

[Edward Strong]

I've had this problem for a while but I waited until the 1.3 release kit
emerged before raising this, unfortunately it has not resolved my problem.

When I reboot the PS3, the last thing to be displayed is:

Synchronizing SCSI cache for disk sda
Synchronizing SCSI cache for disk sda

Then I get a full hardware crash and have to hit the power switch at the
back.  If I just do a shutdown, this works fine.  This error is
reproducible running both Gentoo and FC6.  I am using a 120gb Fujitsu
drive.  Does anyone know why this might be happening?

Thanks in advance,

Edward
