BSOD When putting computer to sleep

[gregm]

I"m running Windows 7 Ultimate 64 bit version. I noticed after I installed SP1 whenever I put the computer to sleep, the disk churns away for about 5-10 mins and eventually it BSOD - driver power state failure - 0x0000009f


I'e read through various posts and tried a bunch of things but nothing works. All the MS updates have been applied. Im running the latest ATI GPU drivers and all the software on my machine is up to date according to Secunia PSI.


Any ideas? I've attached the mini dump.

Fixed it - ran windbg and it pointed to the Realtek NIC driver. A new version was released last month which I installed and problem resolved
