I have a shiny new Haswell notebook (Lenovo T440s), where with 3.11 processor power management didn't work, so I got 3.12-rc5 installed. Worked fine for a few days, then today it no longer boots and inspection yields... # dd if=/dev/sda count=1 |od -t c |tr -d " " 512 bytes (512 B) copied, 0.00115806 s, 442 kB/s 0000000 13.00000\nalsa:hw 0000020 C0D0\t99.00000\nal 0000040 sa:hwC0D3\t99.000 0000060 00\nbacklight:acp 0000100 i_video0\t73.0000 0000120 0\nbacklight:acpi 0000140 _video0-power\t10 0000160 0.00000\nbackligh 0000200 t:intel_backligh 0000220 t\t0.00000\nbackli 0000240 ght:intel_backli 0000260 ght-power\t0.0000 0000300 0\ncpu-consumptio 0000320 n\t0.00000\ncpu-wa 0000340 keups\t875.00000\n 0000360 disk-operations\t 0000400 0.00000\ndisk-ope 0000420 rations-hard\t0.0 0000440 0000\neth0-link-1 0000460 00\t0.00000\neth0- 0000500 link-1000\t0.0000 0000520 0\neth0-link-high 0000540 \t0.00000\neth0-pa 0000560 ckets\t0.00000\net 0000600 h0-powerunsave\t0 0000620 .00000\neth0-up\t0 0000640 .00000\ngpu-opera 0000660 tions\t134.00000\n 0000700radio:hci0\t100.0 00007200000\nradio:phy0\t 0000740100.00000\nradio: 0000760tpacpi_bluetooth 0001000 :-( In order to figure out the reason for this, can you kernel guys maybe a) tell me what is that datastructure? b) can power management be buggy to cause this - I played with powertop tuneables approximately while this happened? ...and point me to a recovery tool/doc for finding the partitions again, "testdisk" tool only found 1 of 3, the least important one at the beginning of disk but not the rest :-( Thank you for any pointers/help! -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
