Ok, this is the workaround that got my SansungX11 intel laptop fix (after a long battle): First off what Phil recommended: Adding the "combined_mode=libata" option to the kernel boot line, in the same way, add the following line to the /etc/modprobe.conf file: options libata atapi_enabled=1 And then as surprising as it may seem, insert a cd or a dvd on your rom and leave it there. Now, I don't have any freezes .... can you believe it ! Here is my parameters for kernel line : noapic nolapic clocksource=acpi_pm quiet combined_mode=libata atapi_enabled=1 I know is not ideal but I spend months on this issue an finally my laptop doesn't freeze ever! No more kernel: ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen! -- Random freezes with "exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2" error https://bugs.launchpad.net/bugs/104581 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
