Thanks for your help.
Problems reported with 1.16e and 1.17 only concerns 810A chips.
Driver 1.16e:
- 810A : 16 bursts + Burst op code fetch + Read multiple + Read line
sometimes does not boot.
8 bursts + same other features seems to fix the problem.
Driver 1.17: (The driver now set by default 810A chips to 8 bursts).
- 810A : 8 bursts + same other features have hang problems (your report).
Disabling Read Multiple (suggested by Stefan) does not fix the
problem.
1.16b which uses 16 bursts + same other features seems to work.
A lot confusing, is'nt it?
Unless the problem is not due to burst and PCI dma features. :(
James, did you try 1.17 with all 810A features disabled and burst 8?
Boot set-up command: ncr53c8xx=burst:3,specf:n
burst:3 means (1<<3) bursts and specf:n means "special features disabled".
If that does not fix your problem, the cause is probably not related to
those 810A special features.
I will look into difference between 1.17 and 1.16b.
Gerard.
PS:
Obviously, 1.17 works fine with my Promise SCSI Ultra, I have heavily
tested it on my system and I use it since last sunday.
I use 1.16e on my Linux development system at work (810 rev. 1) since 10
days and have had no problem at all.
I do what I can ...
