https://bugzilla.kernel.org/show_bug.cgi?id=118401 --- Comment #23 from Navin <navinp1912@xxxxxxxxx> --- 1) First is Why does these lines get printed in 4.2 [ 0.716610] ahci 0000:00:1f.2: version 3.0 [ 0.716620] ahci 0000:00:1f.2: can't find IRQ for PCI INT B; probably buggy MP table where as in 4.4 and 4.6 you don't get to see even the "version 3.0". In your initramfs shell , you should try to see if ahci is actually loaded in /proc/modules 2) One more thing is i see in 4.2 you have this in dmesg libata version 3.00 loaded. I hope in 4.6 also you get that message. You can find it out in your initramfs scripts by doing dmesg | grep -i libata That should tell you that your modules are not loaded/good because of some changes or some other reason like corruption? At the end of initramfs you can do modprobe ahci and see that it prints lsmod | grep ahci That should tell you the reason why it is not printing those messages in dmesg. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
