SLES11 (32-bit) PAE suspend/resume problem

[zencodex]

Hi,

On our Tylersburg server platform with Nehalem X5570 CPU, we encounter a problem of ACPI S3 suspend / resume.

If We tried this system with SLES11 (32-bit) with RAM > 4G, then the kernel is PAE mode and it will reboot instead of resume from S3.

However, if we tried with SLES11 (64-bit) with the same hardware configuration, or if we tried with SLES11 (32-bit) with RAM <= 4G, the system works well to pass S3 suspend/resume test.

How could we solve this issue ?
