2.6.21-rt9 problem : xruns
Hi, I've recently compiled a "vanilla" 2.6.21 kernel, patched with Ingo Molnar's rt-8 patch, as I was unable to compile with rt-7. I needed it because I'm using audio applications (tests were made with FrugalWare, but I don't think it's a distro issue). Everything was allright until I changed my motherboard for an Asrock 4coreDual-Vsta (I formerly used a Nforce4 one), with VIA PT880 Ultra chipset. I've justed switched the hardware, as Linux is neat enough to boot without having to reinstall the whole OS. Since, I get tons of xruns when using RT applications, and the only solution I've found to "fix" it was to disable ACPI at boot time. Moreover, I get this message at boot time : PCI: BIOS bug: MCFG [EMAIL PROTECTED] is not E820 reserved PCI: not using MMCONFIG I've also tested this hardware setup with a UbuntoStudio kernel (2.6.19), and everything works flawlessy (no XRUNS, no kernel messages) ! So here is my question (I'd like to understand what's happening) : - is it a kernel (or patch) issue ? - is it a bad chipset support in the latest kernel versions ? - could this be related to BIOS issues only (I've tried all available versions without any change) ? - should I use special settings in the ".config" in order to avoid these problems ?
