With 2.2.18pre22 I get a lot of scsidisk I/O errors on my parallel port zip.
All pervious versions of 2.2.18pre worked fine. The problem is 100% reproducible and occurs after a long period of inactivity (10 or more minutes)
compiled with #define PPA_DEBUG 1 I get:
ppa_fail(3) from ppa_wait at line 319
if you need more information please contact me directly as I am not on the list
the following partial reversal patch seems to help (but I am not sure it is correct):
--- ppa.c.2.2.18pre22 Mon Nov 20 16:54:36 2000 +++ ppa.c Mon Nov 20 16:54:54 2000 @@ -690,7 +690,7 @@ } } /* Now check to see if the drive is ready to comunicate */ - r = ppa_wait(host_no); /* need ppa_wait() - PJC */ + r = (r_str(ppb) & 0xf0); /* If not, drop back down to the scheduler and wait a timer tick */ if (!(r & 0x80)) return 0;
