[Bug 763037] [NEW] Quite often for no apparent reason syndaemon spins in "select"
Public bug reported:
Binary package hint: xserver-xorg-input-synaptics
I don't know what leads to this, but my macbook pro 15" (5,1) will
suddenly start running its fans and top always shows syndaemon at 100%
CPU. strace shows its just spinning in a select call:
(in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
select(5, [4], NULL, NULL, NULL) = 1 (in [4])
