I'm experiencing a weird hang when attempting to hotplug devices on a 
Marvell88sx card.

I can issue:

cfgadmin -c disconnect <device>

and the device is unconfigured and disconnected without problems.

If I then replace the device (or attempt to use the same device):

cfgadmin -c connect <device>

the command hangs and my syslogs start filling up with:

Apr  1 22:52:00 unknown marvell88sx: [ID 517869 kern.info]      SError interrupt
Apr  1 22:52:00 unknown marvell88sx: [ID 517869 kern.info]              10-bit 
to 8-bit decode error
Apr  1 22:52:00 unknown marvell88sx: [ID 517869 kern.info]              
Disparity error

Eventually the machine becomes non-responsive.

Attempting to re-issue the connect or disconnect commands results in:

bash-3.2# cfgadm -c disconnect sata1/1
Disconnect the port: /devices/[EMAIL PROTECTED],0/pci8086,[EMAIL 
PROTECTED]/pci8086,[EMAIL PROTECTED],3/pci11ab,[EMAIL PROTECTED]:1
This operation will disable activity on the SATA port
Continue (yes/no)? yes
cfgadm: Hardware specific failure: Driver ioctl failed I/O error


Anyone experienced this?
