If someone still "listens" to this bug - short resume of current situation: * Starting somewhere with Feisty Linux kernel started to remove old IDE drivers and replaced them with PATA drivers (nice way to introduce regressions, as it seems); * Alan Cox (re)wrote HighPoint group of drivers during that process, including shiny new one pata_hpt37x; * In result, new driver can't find hard disks connected to lot of controllers, web is full of such reports for some two years; * It feels like no one cares, because you should use better [tm] SATA controllers instead of this broken cruft (partly I agree);
Returning to technical side of problem, with boring and extensive testing I have come to conclusion that problem is wrongly detected bus speed. New pata_hpt37x gives me 66Hz for my controller (details see in lspci output attached above), but Dapper, which has last working version of old IDE driver, indicates it uses 33Hz bus speed. As it's mentioned in this b.k.o bug report (http://bugzilla.kernel.org/show_bug.cgi?id=7703), controllers shouldn't really use 66 Hz bus speed if there is another controllers down the road on PCI bus. Something is broken within detection of bus speed. I will propably ping upstream (Alan Cox) myself, but if someone can help me with getting this fixed - you are welcome. -- SATA disk attached to HPT371N controler is very slow or don't work at all https://bugs.launchpad.net/bugs/162006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
