** Description changed: Binary package hint: linux-source My TV card (Leadtek Winfast TV2000/XP) seems to work only with acpi=off - passed to kernel. When ACPI is enbaled, the picture is just a slideshow, + passed to kernel. When ACPI is enabled, the picture is just a slideshow, trying acpi=noirq makes the slideshow just a little faster. This can be reproduced with any kernel from 2.6.29 to 2.6.32 from mainline ppa, I tried both Hardy LTS and Karmic, didn't try older kernels as they fail to boot. This is no X problem, the behavior can be reproduced even without X and with nvidia module unloaded just by capturing a bit of video. I tried also to recompile bttv driver with IRQF_SHARED or IRQF_DISABLED explicitly declared, it didn't change a thing. The rest of PCI hardware seems to work fine. When the picture is stuttering dmesg reports: [ 78.044297] bttv0: timeout: drop=301 irq=1092/1092, risc=595e2b3c, bits: HSYNC OFLOW [ 78.604537] bttv0: timeout: drop=312 irq=1132/1132, risc=56822b5c, bits: HSYNC OFLOW [ 1081.948327] bttv0: timeout: drop=323 irq=1192/1192, risc=69dad6bc, bits: HSYNC OFLOW + + Edit: The card works normally after disabling C1E in BIOS.
