Comment(by xbaldauf):
Replying to [comment:28 andy]:
> I wonder if what has happened is that too much data is written from the
SD Card unit in the Glamo (which is done by local Glamo DMA), so that it
blows through the allocation of Glamo internal memory and wraps into an
alias that is the framebuffer.
Please also note that the noise does not always come. Often, the
communication between CPU und SD card just fails, without exhibiting the
screen corruption. For example, I've now tested kernel 2.6.24
(http://git.openmoko.org/?p=kernel.git;a=commit;h=a1e97c611253511ffc2d8c45e3e6d6894fa03fa3
, Sat, 23 Aug 2008 10:01:50 +0000 (11:01 +0100) ), and I now also
experienced this bug:
glamo-mci glamo-mci.0: Error after cmd: 0x8121
glamo-mci glamo-mci.0: Error after cmd: 0x8123
mmcblk0: error -84 sending read/write command
end_request: I/O error, dev mmcblk0, sector 1992412
glamo-mci glamo-mci.0: Error after cmd: 0x121
glamo-mci glamo-mci.0: Error after cmd: 0x123
mmcblk0: error -84 sending read/write command
end_request: I/O error, dev mmcblk0, sector 1992412
glamo-mci glamo-mci.0: Error after cmd: 0x8121
glamo-mci glamo-mci.0: Error after cmd: 0x8123
mmcblk0: error -84 sending read/write command
end_request: I/O error, dev mmcblk0, sector 1992412
glamo-mci glamo-mci.0: Error after cmd: 0x121
glamo-mci glamo-mci.0: Error after cmd: 0x123
mmcblk0: error -84 sending read/write command
However, I did not see any screen corruption, I just could not tap button
screen anymore (the application "qpe" did not react). I could kill "qpe"
from the command line successfully, but the screen did change either
(maybe the X server was affected, too). I could not access the filesystem
anymore for new commands, but old commands like "dmesg" (I presume which
were cached fully into RAM) still have been working.
Having tested this under 2.6.24, the comment
Replying to [comment:22 xbaldauf]:
> I've never experienced this bug under kernel 2.6.24 AFAIK.
is now wrong. :-(
So maybe the screen corruption and the presumed DMA-wise overwrite is just
a consequence of the communication problem between CPU and SD-card, and
not the cause, but I do not know...

Comment(by lindi):
I upgraded to andy-tracking bc49de906ce5a6e39a4bc9a46ab33af09b93295f and
noticed that now the deconfig file has
CONFIG_ANDROID_RAM_CONSOLE -- however, drivers/staging/android/ is not
included so I don't know where the actual code is.

Steps to reproduce:
1) git clone git://git.openmoko.org/git/kernel.git neolinux.2
2) cd neolinux.2
3) git checkout -b lindi-andy-tracking origin/andy-tracking
4) mkdir GTA02
5) cp arch/arm/configs/gta02_moredrivers_defconfig GTA02/.config
6) ./build GTA02 dummy
Expected results:
6) kernel builds from source
Actual results:
6) build fails with

Comment(by xbaldauf):
I've been thinking about this issue even further, and moved my root
filesystem from my 8GB "Kingston SDC4/8GB" to the 512MB card which was
included in the freerunner shipping box. This was quite a pain because I
had to omit|delete a lot.
However, after logging in and placing and receiving calls, I have not got
the crash, so far...
Could it be that the communication problem somewhere between CPU and SDHC-
card is, indeed, at the SDHC-card end?
I've been looking for reports of problems with this SDHC card, did not
find any, but I found this report:
http://wiki.openmoko.org/wiki/Supported_microSD_cards/SD-C02G
This looks pretty familiar... "unreliable behavior if the GSM modem is
activated".
So it seems that there is at least one other user with the same problem.
Could it be that there is electromagnetic noise coming from GSM impacting
the card?

Comment(by andy):
This should be fixed with
http://git.openmoko.org/?p=kernel.git;a=commit;h=1c6a91fef7cb2e0fc4f41ddcfff74565b2a7659e
it was just the stock configs lacking some new config options.

Comment(by arhuaco):
Joerg, I apologize if I seemed rude with you in the last update of this
ticket, because I was. I know you really tried to help me do some progress
with my task both via private email and on IRC. Thanks for that, really.
It's just that we had misleading information around and that is not your
fault.
I updated this wiki page and I hope it makes more sense now.
http://wiki.openmoko.org/wiki/Recording_audio
I'll assume the ALSA state we have there works.
