Yes, and one time I noted that after the screen was full of random data, after some seconds from the middle line to the bottom line there was a random screen update, it was fast, but I remember it was linear from up to down. Just now I'm not able to reproduce, I do not know if it's due to a good GSM coverage here.

SD Card read/write errors and NSOD
I'm experiencing read/write error on my 8GB SD card Kingston C08G SDC4/8GB 07 (wiki reports this card shoud work!) with 2.6.28 shr-testing kernel and with 2.6.24 from 2008.12, followed some times by NSOD (Noise Screen of Dead). This does not happen when GSM is off. I found a similiar problem on http://docs.openmoko.org/trac/ticket/2217 , the difference is that I have the problem with 2.6.24 kernel too! (I followed the suggestion to down the glamo clock and the slow memory without success) Before updating the ticket with my details I'd like to know if there is kernel version suited to test this better, and have community feedback to know it this problem affects ather peoples too. Steps to reproduce: ssh to freerunner and type: while true do if=/dev/zero of=/path/to/sd/somefile bs=1024 count=10 sync done while the script is running, operating GSM (call,sms, etc.) randomly reproduces the problem.
