Hot plug sata causes error in 2.6.18 (FC6)

[ocgltd]

I have a clean Fedora Core 6 installation, kernel 2.6.18. When I hot plug my sata drive, I get the following error:

Nov 16 09:06:24 vmhost kernel: ata2: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0x2 frozen

Can anyone offer insite? (In case it's relevant, the hard drive is an Addonics Saturn drive bay connected to SATA on the Asus DSBF motherboard).

According to the vendor, hot swap is supported in kernel 2.4 and up....so I can't explain why it's choking.

Thanks,
