Subject2.2.18pre22: ppa_fail(3) from ppa_wait at line 319
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):

+ r = (r_str(ppb) & 0xf0);
/* If not, drop back down to the scheduler and wait a timer tick

if (!(r & 0x80))
return 0;
