Subject: stb0899 i2c communication broken after suspend
Date: Fri, 31 Jul 2009 18:44:13 +0200 [thread overview]
Message-ID: <4A731F5D.7000904@jusst.de> (raw)
I made an interesting observation with the stb0899 drivers. If the
system was in suspend to ram state (no matter if dvb modules were
unloaded before or not) the i2c communication of stb0899 driver and
chipset seems to be somewhat broken. Tuning to dvb-s channels still
works as expected, but tuning to dvb-s2 channels is completely broken.
The system log shows this error on the first tuning approach:
stb0899_write_s2reg ERR (1), Device=[0xf3fc], Base Address=[0x00000460],
Offset=[0xf34c], Data=[0x00000000], status=-121
Has anyone seen a similar behaviour or has any ideas?
This happens on latest v4l-dvb head and kernel 2.6.29
