Hi,

With 2.6.27-9-server I'm unable to access external disks connected to the 
JMicron USB controller.
With previous kernels, I was able to do so, without problem.

lspci:
0a:00.0 SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI 
Controller (rev 02)

psusb:
Bus 007 Device 010: ID 152d:2338 JMicron Technology Corp. / JMicron USA 
Technology Corp. JM20337 Hi-Speed USB to SATA & PATA Combo Bridge

dmesg:
