Was this behavior observed before the OS upgrade? > Are there any known issues with a pvr250 + 500 in the same box?

I don't know what Linux normally does in response to an NMI, but I would think something would get written to /var/log/messages. Is there anything there? A flaky PCI chipset or strange PCI interaction can cause the system to reboot, since the Northbridge is in charge of the memory and memory region mappings (e.g ROM shadows) and the Southbridge is in charge of a lot of the legacy PC IO devices. If you can dig up the errata sheets for the VT8377 Northbridge, VT8235 Southbridge, and Hint Corp HB6 PCI-PCI bridge, you may find the conditions under which a hang or reboot could occur. > regards > > jp > > [EMAIL PROTECTED]:/proc# cat /proc/version > Linux version 2.6.24.5-smp ([EMAIL PROTECTED]) (gcc version 4.2.3) #2 SMP Wed > Apr 30 13:41:38 CDT 2008 > > [EMAIL PROTECTED]:/var/log# dmesg | grep ivtv > ivtv: Start initialization, version 1.1.0 > ivtv0: Initializing card #0 > ivtv0: Autodetected Hauppauge card (cx23416 based) > ivtv0: Unreasonably low latency timer, setting to 64 (was 32) > ivtv0: Autodetected Hauppauge WinTV PVR-250 > tuner 0-0061: chip found @ 0xc2 (ivtv i2c driver #0) > saa7115 0-0021: saa7115 found (1f7115d0e100000) @ 0x42 (ivtv i2c driver #0) > msp3400 0-0040: MSP4448G-A2 found @ 0x80 (ivtv i2c driver #0) > ivtv0: Registered device video0 for encoder MPG (4096 kB) > ivtv0: Registered device video32 for encoder YUV (2048 kB) > ivtv0: Registered device vbi0 for encoder VBI (1024 kB) > ivtv0: Registered device video24 for encoder PCM (320 kB) > ivtv0: Initialized card #0: Hauppauge WinTV PVR-250 > ivtv1: Initializing card #1 > ivtv1: Autodetected Hauppauge card (cx23416 based) > ivtv1: Unreasonably low latency timer, setting to 64 (was 32) > tuner 1-0043: chip found @ 0x86 (ivtv i2c driver #1) > tuner 1-0060: chip found @ 0xc0 (ivtv i2c driver #1) > tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #1) > ivtv1: Autodetected WinTV PVR 500 (unit #1) > cx25840 1-0044: cx25843-24 found @ 0x88 (ivtv i2c driver #1) > wm8775 1-001b: chip found @ 0x36 (ivtv i2c driver #1) > ivtv1: Registered device video1 for encoder MPG (4096 kB) > ivtv1: Registered device video33 for encoder YUV (2048 kB) > ivtv1: Registered device vbi1 for encoder VBI (1024 kB) > ivtv1: Registered device video25 for encoder PCM (320 kB) > ivtv1: Registered device radio1 for encoder radio > ivtv1: Initialized card #1: WinTV PVR 500 (unit #1) > ivtv2: Initializing card #2 > ivtv2: Autodetected Hauppauge card (cx23416 based) > ivtv2: Unreasonably low latency timer, setting to 64 (was 32) > tuner 2-0043: chip found @ 0x86 (ivtv i2c driver #2) > tuner 2-0061: chip found @ 0xc2 (ivtv i2c driver #2) > cx25840 2-0044: cx25843-24 found @ 0x88 (ivtv i2c driver #2) > wm8775 2-001b: chip found @ 0x36 (ivtv i2c driver #2) > ivtv2: Correcting tveeprom data: no radio present on second unit > ivtv2: Autodetected WinTV PVR 500 (unit #2) > ivtv2: Registered device video2 for encoder MPG (4096 kB) > ivtv2: Registered device video34 for encoder YUV (2048 kB) > ivtv2: Registered device vbi2 for encoder VBI (1024 kB) > ivtv2: Registered device video26 for encoder PCM (320 kB) > ivtv2: Initialized card #2: WinTV PVR 500 (unit #2) > ivtv: End initialization > ivtv0: Loaded v4l-cx2341x-enc.fw firmware (376836 bytes) > ivtv0: Encoder revision: 0x02060039 > ivtv1: Loaded v4l-cx2341x-enc.fw firmware (376836 bytes) > ivtv1: Encoder revision: 0x02060039 > ivtv2: Loaded v4l-cx2341x-enc.fw firmware (376836 bytes) > ivtv2: Encoder revision: 0x02060039 > > [EMAIL PROTECTED]:/var/log# lspci -v > 00:00.0 Host bridge: VIA Technologies, Inc.

Your host bridge can only transfer (8-2)*4 = 24 bytes at a time as a master, if running at 33 MHz. You might try increasing it to 16 or 32 using setpci. > 00:01.0 PCI bridge: VIA Technologies, Inc.

You could try moving the PVR-250 over to bus segment 2 or the PVR-500 over to bus segment 0, to see if things are better when they're on the same bus segment.
