the 53c700 driver pb on c110/d380

Hello James,

as well on c110 as on d380 I always get following pb with this driver for the ncr53c710 chip (scsi narrow s-e external connection), after 2 or 3 untar/rm iterations (obviously this is just an easy way to reproduce this pb which hapen more frequently in day to day life cycle):

(I grabe it from kernel log to show the timestamp)

Some I had to force the reboot of system, some other it panics with some "ccio_alloc_range() I/O MMU..." (most probably "I/O MMU is out of mapping resources.")

Any idea why this 'phase mismatch' hapened?

Tia,

PS: btw I just start to look in more details code but I don't undertand how this hunk:

#ifdef NCR_700_DEBUG
#define STATIC
#else
#define STATIC static
#endif

would help debuging? (I understand that __inline__ would be remove but static?)
