I really don't think that it's relevant here whether something is "officially" supported by the vendor or not. All that matters is sufficient testing... > Same for "hpet-force-enable-on-vt8235-37-chipsets.patch" (I use this > one on my Asrock P4VT8+ motherboard (VT8237 based) with no pb). What!?!?!? Why did nobody tell me that VT8235 *does* actually have a HPET implementation? ;) I've been investigating this during a couple evenings some months ago, with apparently negative result for my VT8235 (blank I/O area at the place where VT8237 has its HPET, and I wasn't able to activate anything), which I then reported on LKML. And now you report that one found that it's actually possible. Yay!! I'm going to test this patch on my EPOX 8K5A2+ (VT8235, i.e. PCI ID 0x3177). I originally thought that having a HPET doesn't matter much due to other timers being available, but it seems it actually matters a LOT due to less timer wakeups etc. Thanks for the hint, Andreas Mohr _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
