i2c-i801 vs. ACPI driver to access SMBUS

2014-08-06 Thread Christian Schmidt
Hi all, I have a small issue with the i2c-i801 driver. It does not register the i2c adaptor due to an ACPI resource conflict: [11074.459747] ACPI Warning: SystemIO range 0xf000-0xf01f conflicts with OpRegion 0xf000-0xf00f (\_SB_.PCI0.SBUS.SMBI)

kworkers for dm-crypt locked to CPU core 0?

2013-03-25 Thread Christian Schmidt
Hi everyone, I am trying to troubleshoot some strange performance issues I am seeing on a machine of mine. Said machine had 10 drives mapped via separate dm-crypt instances. The aggregate (read) throughput seems to hover around 120-130MB/s (looking at iostat -x -d) when running an instance of dd

Hi all, I could not find good documentation anywhere on the memory usage of linux, or rather, how to interpret the output of the various tools dealing with memory consumption. First of, generally - there's resident, virtual and shared memory for each process, and global buffers/cache. Global

Dear all, How do I actually low-level format a floppy disk in an USB-Floppy-Disk-Drive? I tried as with usual drives, using fdformat: [~]>fdformat /dev/sdd Could not determine current format type: Invalid argument But setting the format failed as well: [~]>setfdprm -p /dev/sdd 1440/1440
