Looking at the source code of ncr53c8xx.c at line 7525 I see:
#if 0 case 3: /* STATUS phase */ nxtdsp = NCB_SCRIPT_PHYS (np, dispatch); break; #endif case 6: /* MSG OUT phase */ np->scripth->nxtdsp_go_on[0] = cpu_to_scr(dsp + 8); if (dsp == NCB_SCRIPT_PHYS (np, send_ident)) { cp->host_status = HS_BUSY; nxtdsp = NCB_SCRIPTH_PHYS (np, clratn_go_on); } else if (dsp == NCB_SCRIPTH_PHYS (np, send_wdtr) || dsp == NCB_SCRIPTH_PHYS (np, send_sdtr)) { nxtdsp = NCB_SCRIPTH_PHYS (np, nego_bad_phase); } break; #if 0 case 7: /* MSG IN phase */ nxtdsp = NCB_SCRIPT_PHYS (np, clrack); break; #endif
So code to handle these errors seems to be disabled. I tried enabling it but I still got the problem.
After the phase change I get:
May 7 15:34:47 leaf kernel: attempt to access beyond end of device May 7 15:34:47 leaf kernel: 08:06: rw=0, want=1334509569, limit=704907
as before
Presumably some descriptor tables for the device have been trashed. Is this the real problem and is the phase error just a symptom?
