Hello all,
I am using 3.13-rc1 kernel on iMX6SL processor. My filesystem is in
eMMC running SDR50.
Is anyone here encountered these problem and if there's any existing
patch that I can get?.
Regards,
john

How reproducable is this? I notice you're using 3.13-rc1 too, it could
be the bug has already been fixed in a later kernel version. -rc1
kernels are really the "fresh after lots of new feature merging" kernels
which should always be expected to be rather buggy.
Linux kernel "release candidates" are not "we think this is going to be
a final kernel, please test it" but -rc1 marks the end of the new
feature merging and the beginning of the stablisation phase.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
I ran the kernel in our custom board and I've seen the error after
(sometimes 10 minutes after) the reboot and sometimes my board ran for
an hour or so before it happened.
I will try the 3.13-rc8 today and will see if the said bug still exist or not.

Hello all,
Just to confirm that the error I posted previously exist in 3.13
released. Just be noted that some patches related to eMMC/sdhci has
been applied in order to boot the 3.13 on my board.
Addition to that, I was getting additional errors (please see below):
- It happened during the reboot.

What are the steps to reproduce this? Which SoC are you using?

hi,
Do you use gcc 4.8.1? If so, maybe you should look at following link
to see whether it's a similar issue.

Hi Fabio,
Attached are the two patch files that I applied in the 3.13 released
so that the kernel will detect my eMMC in DDR50.
(let me correct my previous email, I was mentioning SDR50 but it
should be DDR50).
eMMC info:
clock: 52000000 Hz
actual clock: 49500000 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 3 (8 bits)
timing spec: 1 (mmc high-speed)
signal voltage: 0 (3.30 V)
I reboot my device often and it shows during the reboot.
Regards,
john

Hi,
Or you can use the latest linaro 4.8.x toolchain, which has been applied that patch:
http://releases.linaro.org/13.12/components/toolchain/binaries/
Please select this one to try:
gcc-linaro-arm-linux-gnueabihf-4.8-2013.12_linux.tar.bz2
