[Bug 421276] Re: USB remote stops working

[Mihaly]

I'm seeing this problem too.  Occasionally (maybe once a week) the
frontend stops responding to IR commands.  I believe it is only
happening while watching video (ie. live tv or a recording, not while
the frontend is displaying menu).

Running top shows nothing unusual (90%+ idle).  I ran an strace on lircd
during a no-response, the output is below:

)  = 1 (in [6])
gettimeofday({1268909834, 784876}, NULL) = 0
read(6, "\1\0\t\0\0\0\0\0"..., 8)       = 8
gettimeofday({1268909834, 784945}, NULL) = 0
select(9, [4 5 6 8], NULL, NULL, {0, 20000}) = 1 (in [6], left {0, 19998})
gettimeofday({1268909834, 784993}, NULL) = 0
read(6, "F\0\1\0\371\0\0\0"..., 8)      = 8
gettimeofday({1268909834, 785029}, NULL) = 0
gettimeofday({1268909834, 785053}, NULL) = 0
write(5, "00010046000000f9 00 chup DVICO\n"..., 31) = 31
write(8, "00010046000000f9 00 chup DVICO\n"..., 31) = 31
gettimeofday({1268909834, 785191}, NULL) = 0
select(9, [4 5 6 8], NULL, NULL, NULL)  = 1 (in [6])
gettimeofday({1268909834, 912832}, NULL) = 0
read(6, "\1\0\t\0\0\0\0\0"..., 8)       = 8
gettimeofday({1268909834, 912889}, NULL) = 0
select(9, [4 5 6 8], NULL, NULL, {0, 20000}) = 1 (in [6], left {0, 19992})
gettimeofday({1268909834, 912951}, NULL) = 0
read(6, "F\0\1\0\371\200\0\0"..., 8)    = 8
gettimeofday({1268909834, 912986}, NULL) = 0
gettimeofday({1268909834, 913010}, NULL) = 0
write(5, "00010046000000f9 01 chup DVICO\n"..., 31) = 31
write(8, "00010046000000f9 01 chup DVICO\n"..., 31) = 31
gettimeofday({1268909834, 913150}, NULL) = 0
select(9, [4 5 6 8], NULL, NULL, NULL

which kinda looks ok.  Also, when I ran irw the button presses printed
ok as I clicked on the remote.

So it looks like the remote & the IR software are ok.  Somehow the
commands aren't getting through to the frontend, or the frontend isn't
listening.

BTW, all software versions are as per Ubuntu 9.04.
