Hello All, some days ago I migrated my home-server from a VIA PC2500E (with C7 CPU) to a VIA VB8001 (with VIA Nano). Overall it went quite good, I see only two remaining problems. - 1. SATA Controller With the patch found here: http://lists.freebsd.org/pipermail/freebsd-current/2009-February/003568.html the controller is detected correctly and negotiates SATA300 with the harddisks. It would be nice to have this (or a similar patch) commited. - 2. Power Management The est driver fails to attach to the CPU. This is somewhat OK, as the necessary table in est.c for this specific CPU is missing at the moment. When powerd is started, it usually takes about 3-5 seconds and the system panics. I guess, powerd tries to throttle the CPU down via ACPI oder P4TCC, as there are some levels recognized: dev.cpu.0.freq_levels: 1615/-1 1413/-1 1211/-1 1009/-1 807/-1 605/-1 403/-1 201/-1 dev.p4tcc.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1 2500/-1 1250/-1 The kernel configuration file, crashinfo output and verbose dmesg can be found at http://space.kvedulv.de/vb8001/ if someone wants to look into this.
