I have an HVR-950Q: [44847.234403] tveeprom 0-0050: Hauppauge model 72001, rev B3F0, serial# ******* [44847.294643] tveeprom 0-0050: MAC address is **:**:**:**:**:** [44847.343417] tveeprom 0-0050: tuner model is Xceive XC5000 (idx 150, type 76) [44847.402873] tveeprom 0-0050: TV standards NTSC(M) ATSC/DVB Digital (eeprom 0x88) [44847.465471] tveeprom 0-0050: audio processor is AU8522 (idx 44) [44847.515481] tveeprom 0-0050: decoder processor is AU8522 (idx 42) [44847.567162] tveeprom 0-0050: has no radio, has IR receiver, has no IR transmitter [44847.630272] hauppauge_eeprom: hauppauge eeprom: model=72001 With the au0828, xc5000, and au8522 drivers loaded suspend-to-ram hangs. This never used to be the case on previous (2.6.32ish) kernels but now with the 3.2 kernels that I have been using it is the case. If I simply rmmod those drivers before suspending, both suspend and resume work fine. I'm not sure what more information to provide about this but I am happy to gather and provide whatever information you might want. modinfo says au0828 is version 0.0.2 if that is at all meaningful.
Interestingly enough, if I remove and insert the au0828 enough times, the device will be functional again. Sounds like something racy is happening during insertion?
Additionally: It seems when it's inserted and doesn't work, the following is logged in the kernel message buffer: xc5000: Device not found at addr 0x61 (0xffff) and when it's inserted successfully: xc5000: Successfully identified at address 0x61 xc5000: Firmware has not been loaded previously
Confirmed that the HVR-950q is randomly unable to initialize on recent kernels (since around 2.6.33). Sometimes it will initialize correctly, sometimes it won't. It sometimes gets "stuck" in an unitialized state and won't re-initialize after reinserting or rebooting no matter how many times you try. After some days, it will initialize correctly again. I've most recently tested with linux-3.4.1-rc1.
