It may be marked as expired, I'm fairly confident this bug has been giving me grief for about a year. I've temporarily removed the HVR-1300 from my system to diagnose yet another bug, but still have some syslog notifications from a boot within the past 48 hours on a Kubuntu 13.04 system w/ KDE 4.10.5 & Wine repo & Chrome repo.
I've also noticed differences between warm/cold boots, and disabling SMP in BIOS decreases likelihood of boot failures. Out of eight failed boots, the readreg error line is always identical. I suspect there are more people with similar cards suffering: http://forums.gentoo.org/viewtopic-p-6620113.html#6620113 grep -i cx /var/log/syslog Jul 5 21:50:05 pentiumiv kernel: [ 22.035469] cx2388x alsa driver version 0.0.9 loaded Jul 5 21:50:05 pentiumiv kernel: [ 22.091811] cx88[0]: subsystem: 0070:9601, board: Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encoder [card=56,autodetected], frontend(s): 1 Jul 5 21:50:05 pentiumiv kernel: [ 22.105055] cx88/2: cx2388x MPEG-TS Driver Manager version 0.0.9 loaded Jul 5 21:50:05 pentiumiv kernel: [ 22.139100] cx88/0: cx2388x v4l2 driver version 0.0.9 loaded Jul 5 21:50:05 pentiumiv kernel: [ 22.215510] cx88[0]: i2c init: enabling analog demod on HVR1300/3000/4000 tuner Jul 5 21:50:05 pentiumiv kernel: [ 22.516724] tveeprom 0-0050: audio processor is CX880 (idx 30) Jul 5 21:50:05 pentiumiv kernel: [ 22.516726] tveeprom 0-0050: decoder processor is CX880 (idx 20) Jul 5 21:50:05 pentiumiv kernel: [ 22.516732] cx88[0]: warning: unknown hauppauge model #96039 Jul 5 21:50:05 pentiumiv kernel: [ 22.516734] cx88[0]: hauppauge eeprom: model=96039 Jul 5 21:50:05 pentiumiv kernel: [ 22.671683] cx88[0]/1: CX88x/0: ALSA support for cx2388x boards Jul 5 21:50:05 pentiumiv kernel: [ 22.672220] cx88[0]/2: cx2388x 8802 Driver Manager Jul 5 21:50:05 pentiumiv kernel: [ 22.672493] cx88[0]/2: found at 0000:02:01.2, rev: 5, irq: 22, latency: 64, mmio: 0xfc000000 Jul 5 21:50:05 pentiumiv kernel: [ 22.673295] cx88[0]/0: found at 0000:02:01.0, rev: 5, irq: 22, latency: 64, mmio: 0xfa000000 Jul 5 21:50:05 pentiumiv kernel: [ 22.973316] cx88/2: cx2388x dvb driver version 0.0.9 loaded Jul 5 21:50:05 pentiumiv kernel: [ 22.973324] cx88/2: registering cx8802 driver, type: dvb access: shared Jul 5 21:50:05 pentiumiv kernel: [ 22.973330] cx88[0]/2: subsystem: 0070:9601, board: Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encoder [card=56] Jul 5 21:50:05 pentiumiv kernel: [ 22.973334] cx88[0]/2: cx2388x based DVB/ATSC card Jul 5 21:50:05 pentiumiv kernel: [ 22.973336] cx8802_alloc_frontends() allocating 1 frontend(s) Jul 5 21:50:06 pentiumiv kernel: [ 23.150095] cx22702_readreg: error (reg == 0x1f, ret == -5) Jul 5 21:50:06 pentiumiv kernel: [ 23.150102] cx88[0]/2: frontend initialization failed Jul 5 21:50:06 pentiumiv kernel: [ 23.150108] cx88[0]/2: dvb_register failed (err = -22) Jul 5 21:50:06 pentiumiv kernel: [ 23.150113] cx88[0]/2: cx8802 probe failed, err = -22 Jul 5 21:50:06 pentiumiv kernel: [ 23.274719] wm8775 0-001b: chip found @ 0x36 (cx88[0]) Jul 5 21:50:06 pentiumiv kernel: [ 23.313908] cx88[0]/0: registered device video0 [v4l2] Jul 5 21:50:06 pentiumiv kernel: [ 23.316384] cx88[0]/0: registered device vbi0 Jul 5 21:50:06 pentiumiv kernel: [ 23.317229] cx88[0]/0: registered device radio0 Jul 5 21:50:06 pentiumiv kernel: [ 23.411984] cx2388x blackbird driver version 0.0.9 loaded Jul 5 21:50:06 pentiumiv kernel: [ 23.411992] cx88/2: registering cx8802 driver, type: blackbird access: shared Jul 5 21:50:06 pentiumiv kernel: [ 23.411998] cx88[0]/2: subsystem: 0070:9601, board: Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encoder [card=56] Jul 5 21:50:06 pentiumiv kernel: [ 23.412326] cx88[0]/2: cx23416 based mpeg encoder (blackbird reference design) Jul 5 21:50:06 pentiumiv kernel: [ 23.412548] cx88[0]/2-bb: Firmware and/or mailbox pointer not initialized or corrupted Jul 5 21:50:08 pentiumiv kernel: [ 25.923633] cx88[0]/2-bb: Firmware upload successful.
