[Q] touch screen not responding only when sd card is present

[CharlyBrok]

Hi all,
I have a problem with my defy, whitout fall or update the touch screen stop responding.
After some resets & sbf flashing I've noticed that the touch screen is ok only when there is no sdcard.
I've tried over sdcards with no more success.
The sdcard is readable, I can access with adb.
Clockworkmod access the sdcard too.

With sdcard dmesg :
qtouch_force_reset: Forcing HW reset
Unable to get gpio pin num for touch_pwr_enq
touch_write: Error while trying to write 2 bytes
qtouch_set_addr: Can't send obp addr 0x 0
qtouch_process_info_block: Cannot read info object block
qtouch_ts_probe:Cannot read info block -121, checking for bootloader mode.

Without sdcard :
qtouch_force_reset: Forcing HW reset
Unable to get gpio pin num for touch_pwr_en
qtouch_process_info_block: Build version is 0x10
qtouch_process_info_block: Object 5 @ 0x00f2 (9) insts 1 rep_ids 0
qtouch_process_info_block: Object 6 @ 0x00fb (6) insts 1 rep_ids 1
qtouch_process_info_block: Object 38 @ 0x0101 (8) insts 1 rep_ids 0
(...)

Can it be a HW problem ?
What do you think I can do ?

AFAIK, it is HW related..
Best choice, get it to the SC..

Maybe I'll try to change the digitizer (20€ on ebay).
Warranty period is finish.

I want more log,
The goal is to enable logging debug in qtouch_obp_ts
I put in /system/etc/init.d/77debug
Echo 0xFF > /sys/module/qtouch_obp_ts/parameters/tsdebug
But no change at all...
What I am doing wrong ?
