[parisc-linux] K410 SCSI 53c700 issue with PLEXTOR PX-R820T

[Joel Soete]

Sorry for this auto followup but during am i writing previous line I was testing a older vmlinux-2.6.16-pa10 and this pb was 
showing his face after a bit more then 30min of loop test:
scsi1: (3:0) phase mismatch at 01e8, phase IO CD MSG BSY REQ MSG IN
scsi1: Bus Reset detected, executing command 2ca36620, slot 2fd18520, dsp 001c81e8[01e8]
  failing command because of reset, slot 2fd18520, cmnd 2ca36620
  failing command because of reset, slot 2fd1864c, cmnd 2ca368e0
  failing command because of reset, slot 2fd18778, cmnd 2ca36200
  failing command because of reset, slot 2fd188a4, cmnd 149c6320

but:
   - one time (after about 45 min)
   - and the test can continue (while in 2.6.18-rc1-pa1 it finished always by panicing
     because ccio finished by being overloaded.
