If my USB DVB-T TV Card (Hauppauge WinTV-HVR 900) is plugged in my Laptop (Thinkpad T43 2668), when the system is suspended, it won't successfully resume. The resume process seems already started: external USB Hard disk, USB keyboard, USB webcam have all received power while the monitor still stays black screen. The process will hang at this state but if the USB TV Card is disconnected at this point, the process will continue and eventually the resume will be successful. (There is typically ~40 seconds between disconnection of the TV Card and the resume finishes during which there seems no obvious activities with the laptop e.g. disk I/O).
From the kernel log, such a pause could be observed:
...
Oct 2 14:54:58 strasbourg kernel: [ 335.492394] xc2028 0-0061: creating new instance
Oct 2 14:54:58 strasbourg kernel: [ 335.492396] xc2028 0-0061: type set to XCeive xc2028/xc3028 tuner
Oct 2 14:54:58 strasbourg kernel: [ 335.492404] firmware: requesting xc3028-v27.fw
Oct 2 14:54:58 strasbourg kernel: [ 395.492043] xc2028 0-0061: Error: firmware xc3028-v27.fw not found.
Oct 2 14:54:58 strasbourg kernel: [ 395.492472] tvp5150 debug 0-005c: i2c i/o error: rc == -71 (should be 1)
...
Although the firmware file is missing in the default installation of Intrepid as described in Bug #278656, my system has had the firmware installed manually before doing the suspend/resume test and the TV card is working well before suspend.
If em28xx-new, the TV Card driver/kernel modules maintained by Markus Rechberger, are compiled and installed, there wil be no problem with suspend/resume. |
