similar to: [CENTOS6] mtrr_cleanup: can not find optimal value - during server startup

Hi, I have server that has been running 5.x - 5.8 for a few years without issue and decided to move it to a fresh install of 6.2. First thing I noticed is a good part of the log has these mtrr messages finally ending with "mtrr_cleanup: can not find optimal value" and "please specify mtrr_gran_size/mtrr_chunk_size". I have been searching around and reading the kernel docs

Good Day All, Today I looked at the dmesg log and I notice that the following messages regarding mtrr_gran_size/mtrr_chunk_size. I am currently running CentOS 6.3 and I installed CentOS 6.2 and 6.1 and I was seeing the same errors. When I installed CentOS 5.8 on the same laptop I do not see these errors. $ lsb_release -a LSB Version:

CentOS 6.4, current, Dell PE R720. Had an issue today with a bus error, and googling only found two year old references to problems with non-Dell drives (we just added two WD Reds, and mdadm raided them). So, looking through dmesg and /var/log/messages, I ran into a *lot* of G gran_size: 128K chunk_size: 256K num_reg: 10 lose cover RAM: 0G gran_size: 128K chunk_size:

Does anybody please have any experience with the following CentOS 6 warnings in logwatch?

Dear CentOS users, I run a small Facebook game at a CentOS 6.3 machine with PostgreSQL 8.4.3 + few PHP scripts + 1 Perl daemon and even though the server worked ok, I've suggested my users to double up the RAM to 32 GB and they have collected money for that. Now my problem is that I don't know, which knob to turn and how to really use the additional memory. Below is my top output at the

I'm trying to figure out why 2 machines have a "hard I/O lock" on the HDD when running EL6. I have 4 identical machines, all were stable with EL5. 2 work great with EL6, 2 do not. I've checked momtherboard BIOS versions and settings, SAS controller BIOS versions and settings, they are the same between the working and non- working systems. When booting a non-working system,

When a whole-file checksum is performed, hashing was done in 64 byte blocks, causing overhead and limiting performance. Testing showed the performance improvement to go up quickly going from 64 to 512 bytes, with diminishing returns above, 4096 was where it seemed to plateau for me. Re-used CHUNK_SIZE (32 kB) as it already exists and should be fine to use here anyway. Noticed this because

Dear llvm developpers, I followed the tutorial to build llvm and clang provided here: https://clang.llvm.org/get_started.html The sources are in sync with subversion repository, and I ended up with more than 30GB of binaries in llvm/bin as shown at the end of this message. I assume I did something wrong, but I did not find any entry in the doc that helps me understand how to reduce the size of

Hy Timo ! I Made some modification in stream_read in zlib. I remove all zlib part, because i don't need this, but i need to read a istream to change it. Well, i create a size_t called supersize, with is a substitute for stream->zs.avail_in. The trouble is, my debug file have a lot of "READ Plugin\n", and i think it's because my read becomes a loop, i think it's because

Dear R forum Please refer to my query captioned Error with function. I had missed in bracket ")" in the return statement and hence I was getting the error. I has struggled for more than 2 hours to find out the problem and only then has posted to the forum. I sincerely apologize to all for consuming your valuable time. Thanks for the efforts at your end.
