Hibernate would crash and restart sometimes going in and would crash and restart about 50% on resume. Very frustrating. I was blaming the video drivers since my previous build (AMD/nvidia) would sometimes not reinitialize the display coming out of standby and it definitely changed behavior with different video drivers.

Yesterday I found http://support.microsoft.com/kb/889673 and installed the hotfix. Standby works perfectly ever since! I have not tried hibernate again, since standby works so good now.

I hope this helps others who were frustrated by this issue.
I have the same problem. I have 2 drives in RAID0 on the SATA 1 & 3 connectors, a burner on the Intel IDE port, and added 2 IDE drives on the JMicron IDE ports.
Everything works fine until the system goes into 'Standby' (sleep) mode. When it resumes, the drives on the JMicron IDE port have disappeared! The only way I can get them back is to reboot.
I had the 1305 BIOS, switched to the 1503 BIOS and same issue.
I did the Microsoft 'hotfix' and it did nothing.
Any suggestions?
