Realtek card reader not recognized

Hi! I installed v4.4.1 to an SD card (from Windows, then from Linux, with same results). After booting, it can not find the SD card. (so it does not finish loading) I also booted it from an USB stick, and tried to Access the card reader from there, also without success. I tried 32 and 64 bit kernels...

Re: LZ4 - Extremely Fast Compression Algorithm

There is a multi-threaded version here:
https://github.com/t-mat/lz4mt

Please consider it.
Note: I have not tested/used it at all. Will report when I do, if desired.

Rationale: Atom CPUs a are really really slow, but many have more than one core.

Re: Weird dd behavior

gernot wrote:It is how the kernel handle the device, check the blocksize of it.
blockdev --getbsz /dev/sdb

It says 4096.

Is this related to pagesize (of CPU architecture)?

Still I'm surprised the kernel did not wait for 8 512 byte blocks and perform a single write. I guess I was too long absent from LKML. ;)

Re: Recovery from a split image

You can also "virtually" concatenate the files, without making a new copy.
With losetup and mdadm, for example. And then mount the resulting device file.

Re: NTFS partition imaging

Note that writing to NTFS under linux (using ntfs-3g) can be pathetically slow. When writing big files (as in a backup image file) the big_writes mount option (see man ntfs-3g) helps a lot (write speed up to actual hardware limit). PS: Not much traffic here, eh? Only after posting I noticed that thi...

Weird dd behavior

Using v4.7.1 64 bit standard kernel I run: dd if=/dev/sda of=/dev/sdb and the iostat 2 to check things. To my surprise iostat reported about 22 MB/s read activity on both drives and also about 5 MB/s write on sdb. Adding bs=1M "fixed" it (read 130 MB/s on sdb and 130 MB/s write on sdb). Wh...

Re: Boot problem - net setup!

For most Windows 7 issues, use the Windows 7 installation DVD. Start it, then after it is loaded you get a menu presented. There are options like "Repair the PC", "restore from backup" and similar. (do not choose "Install", that would overwrite the current system, allth...

Automatic 64 bit kernel choice with grub

Hi! In v3.0.0 isolinux is set to automatically use the 64bit kernel if CPU is capable. Also there is a GRUB2 boot configuration. As grub2 too supports automatic 64-bit capability detection, it would be nice to use it, to be consistent with the isolinux config. Regards, David PS: There is quite an ab...

Re: How do I boot gag, ranish, etc. from USB using GRUB

I have put SystemRescueCd on my ntfs USB stick that has grub4dos as boot loader. I used the grub config at How to install SystemRescueCd on an USB-stick as starting point. I made some slight modifications. First, I put all SystemRescueCd files into a subdirectory on the stick, called sysresCD (could...

Hi!

The FAQ says: To subscribe to a topic, reply to the topic with the subscribe checkbox checked or click the “Subscribe topic” link within the topic itself.

But I can not find those options. Is it turned off?

Mailing lists

Hi!

Is the Systemrescuecd-announce the only mail list?

The archives at http://sourceforge.net/mailarchive/foru ... d-announce require a login (and even after that I can not access them). Is that on purpose?

Regards,
David
