&gt;&gt;&nbsp;Dear&nbsp;all,
&gt;&gt;&nbsp;
&gt;&gt;&nbsp;I&nbsp;find&nbsp;the&nbsp;kernel&nbsp;2.6.28&nbsp;is&nbsp;supported&nbsp;ext3&nbsp;for&nbsp;SD&nbsp;card&nbsp;not&nbsp;well.
&gt;&gt;&nbsp;The&nbsp;external&nbsp;SD&nbsp;card&nbsp;is&nbsp;formatted&nbsp;with&nbsp;ext3,&nbsp;and&nbsp;when&nbsp;removal&nbsp;from
&gt;&gt;&nbsp;sd&nbsp;slot,&nbsp;it&nbsp;prints&nbsp;below&nbsp;ext3_abort&nbsp;msg.&nbsp;Such&nbsp;message&nbsp;isn't&nbsp;occurred&nbsp;at
&gt;&gt;&nbsp;Linux&nbsp;2.6.23&nbsp;and&nbsp;2.6.27.

&gt;&gt;&nbsp;Besides,&nbsp;I&nbsp;find&nbsp;when&nbsp;system&nbsp;goes&nbsp;to&nbsp;suspend,&nbsp;when&nbsp;we&nbsp;remove&nbsp;sd&nbsp;card
&gt;&gt;&nbsp;after&nbsp;the&nbsp;system&nbsp;has&nbsp;already&nbsp;suspended.&nbsp;Then,&nbsp;press&nbsp;wakeup&nbsp;button,&nbsp;the
&gt;&gt;&nbsp;system&nbsp;can't&nbsp;wakeup.&nbsp;It&nbsp;sounds&nbsp;happens
&gt;&gt;&nbsp;deadlock&nbsp;at&nbsp;__fsync_super,&nbsp;which&nbsp;call&nbsp;stack&nbsp;likes&nbsp;below:
&gt;&gt;&nbsp;mmc_remove_card--&gt;device_del--&gt;mmc_blk_remove--&gt;del_gendisk
&gt;&gt;&nbsp;
&gt;&gt;&nbsp;Such&nbsp;action&nbsp;is&nbsp;ok&nbsp;at&nbsp;Linux&nbsp;2.6.23&nbsp;and&nbsp;2.6.27.&nbsp;And&nbsp;sd&nbsp;card&nbsp;with&nbsp;vfat&nbsp;at
&gt;&gt;&nbsp;2.6.28&nbsp;is&nbsp;ok.
&gt;&gt;&nbsp;
&gt;&gt;&nbsp;Does&nbsp;anyone&nbsp;know&nbsp;what&nbsp;happening&nbsp;for&nbsp;ext3&nbsp;at&nbsp;2.6.28&nbsp;(&nbsp;or&nbsp;from&nbsp;2.6.28)?
&gt;&gt;&nbsp;Any&nbsp;solutions&nbsp;for&nbsp;such&nbsp;issue?
&gt;
&gt;You&nbsp;popped&nbsp;the&nbsp;card&nbsp;out&nbsp;without&nbsp;unmounting&nbsp;the&nbsp;filesystem&nbsp;I&nbsp;guess&nbsp;?
&gt;&gt;&nbsp;
&gt;&gt;&nbsp;Thank&nbsp;you!
