SYMPTOMS
When you start a Windows Vista-based computer, you may receive a Stop 0x50 error message that resembles the following:
This problem occurs on a computer that has the following hardware installed:
- A card bus adapter
- A storage device that is inserted into the card bus adapter
The storage device might be one of the following:
- A secure digital (SD) card
- A compact flash (CF) card
- An external Serial Advanced Technology Attachment (eSATA) hard disk drive that is running in SATA Advanced Host Controller Interface (AHCI) mode
CAUSE
This problem may occur if the resource requirements of the installed devices do not match those requested by the BIOS. In this situation, a rebalance of AHCI registers occurs. This behavior triggers the Stop 0x50 error message.
