[U-Boot-Users] SystemACE error

The reading of the systemace compact flash is periodically setting the
configuration read error (CFGREADERR) bit in the error register.
Has anybody out there seen this behavior or have any ideas?
For instance, just reading the error register when entering and exiting
the systemace_read() in common/cmd_ace.c I see the following output when
using the FAT commands:
=> fatinfo ace 0
fatinfo ace 0
systemace_read: >> error reg=0x0
systemace_read: << error reg=0x0
systemace_read: >> error reg=0x0
systemace_read: << error reg=0x0
systemace_read: >> error reg=0x0
systemace_read: << error reg=0x0
systemace_read: >> error reg=0x0
systemace_read: << error reg=0x80 <<<<<< ERROR!!!!
Partition 1: Filesystem: FAT16 "
The problem manifests itself when the Linux device driver comes up and
tries to identify the device but finds the chip is already in an errror
state.
Thanks,
Jeff Angielski
