No, my device doesn't work with 6Gbps. In kernel 4.14 if my drive was offline, function sata_down_spd_limit() cut down link->sata_spd_limit to 1, so it corresponds to 1.5Gbps, and was working. But it wasn't even try to set limit to 3Gbps.
In my device, unfortunately mask and link->sata_spd_limit is set to INT_MAX, so next bitwise operations doesn't make any sense, because mask is far out of range valid values. Setting link->sata_spd_limit = 0x7 doesn't work (my device is not 6Gbps capable). In patch I cut mask to be not greater than 0x7, not just 0x7. Actually after masking, kernel tries to connect with 3Gbps (mask 0x3) and it succeed. About comment and hard reset. I get your patch and modified it leaving commit message and comment in code untouched. I don't investigate this topic enough. I have to check how working __sata_set_spd_needed() and sata_link_hardreset() functions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783906 Title: Linux 4.15 and onwards fails to initialize some hard drives To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1783906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
