Two days ago, I upgraded my 486dx2/50 gateway from a 1.5 month old
-current to a bleeding-current.
Since upgrading, I haven't been able to make a userland ppp
connection. Trying an interactive term session from inside ppp, I
noticed that it looked like I could not receive what was in my buffer
unless I sent a character through.
example: I type 'a', nothing shows. I type 't', the a appears. I
type '<cr>', the t appears. I type <cr> again, I get OK to appear.
If I go ahead and dial my connection manually and ppp slides into
packet mode, I start getting a bunch of:
sio0: 1 more silo overflow (total 1)
sio0: 1 more silo overflow (total 2)
...
sio0: 1 more silo overflow (total 79)
sio0: 1 more silo overflow (total 80)
(i gave up at this point and bludgeoned the ppp process)
I've tried this from a pentium machine that is also running
bleeding-current and the problem doesn't seem to appear.
I've tried a bunch of different kernel configs with no change in
status.
I'm curious about the 'irc maps' stuff (as seen in the following dmesg
dumps)
WORKING 486:
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
(old kernel, no irq maps stuff, happy happy)
NONWORKING 486 (example 1):
sio0: irq maps: 0x8009 0x8019 0x8009 0x8009
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
(ick.)
NONWORKING 486 (after turning off all but sio0 from visual config):
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: irq maps: 0x1 0x1 0x1 0x1
sio0 at 0x3f8-0x3ff irq 4 flags 0x20010 on isa
sio0: type ST16650A
(identical ick.)
WORKING p100:
sio0: irq maps: 0x1 0x11 0x1 0x1
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
(happy contented config, seemingly. this entire email done over this
connection, through aliasing even.)
Following is a bunch of dmesg's from a few different attempts and
machines:
