hmmm... 2 posts within 12 hrs. not my usual... : )

after having installed the 0.8.2 pdaxQtrom (base, apps, zgcc, java, open office) i've been experiencing some odd behavior of my 4Gb SD card. notably, it is inconsistently mounted, and after going to 'sleep' or closing the clamshell on my 3100, it is no longer recognized by the system -- almost as if it were 'unmounted'.

if i uninstall the sdmmc-module-2.4.20; this behavior does not occur with a 16, 32 or 512Mb SD card. when i reinstall the module -- the behavior occurs with all 3 cards (and the 4gb card...)

any thoughts on how i might troubleshoot this?

(btw -- if i haven't said this before; thanks so much for all the folks who put in the hard work and time on making the zaurus such a GREAT tool. my only wish would be for internal wireless... but, having said that, imho, its a nearly perfect device and the community is a pleasure!)

even more...

this is really maddening.
decided to reload fsck'd all drives. minor mods to sd_mem_ctrl (above) and fstab

*/dev/mmcda1 /mnt/card auto noauto,owner 0 0 *

this line previously had other options *noauto,owner,noatime,iocharset=utf8*

now.. all sd/mmc cards from 16mb to 1gb work fine. the 4gb is recognized and mounted intermittently -- and, when mounted (approx every 4-5 insertions) works properly until the zaurus is placed in suspend mode.

the 4gb cannot be mounted manually, nor can it be fsck'd, formatted, etc... no device appears to be recognized.
this card continues to work properly in 2 different digital cameras (every insertion).

i really think this is a coding/software issue. if anyone has any suggestions as to how i would go about 'tracking' the culprit (whether module or device or whatever), please give me your thoughts.
i really don't need a 4gb card on my digital camera... but don't want to be constrained to 1gb on my z.
