[23:06] <grant___> I'm getting USB buffer underruns on 3.4 which I have to stick with due to the old binary video drivers available for the Pandaboard. The buffer underruns disappear if the system is under load such as when compiling a kernel. I have CONFIG_CPU_FREQ=n, CONFIG_CPU_IDLE=n, and acpi=off. Where else should I look to fix this?
[23:20] <lilstevie> grant___, do you get a stack trace or anything?
[23:21] <grant___> lilstevie: I just get these: "ehci-omap.0: detected DataBufferErr"
[23:21] <grant___> and audible gaps in music streaming via jackd over the ethernet interface which goes over USB
[23:22] <lilstevie> grant___, I would probably file a bug against the kernel package :)
[23:22] <grant___> it's fixed in newer kernels but I have to stick with the old one for video
[23:25] <lilstevie> you could backport the fix
[23:37] <grant___> lilstevie: how could I figure out where the fix is?
