Title: Sd Card Mount Problem + Workaround
Post by: ironstorm on June 16, 2005, 01:52:48 am

I just did a build of OZ the other night:
Linux collie 2.4.18-rmk7-pxa3-embedix #1 Tue, 14 Jun 2005 03:05:30 +0000 armv4l unknown

And when I do a cat /proc/partitions I get:

Quote

major minor  #blocks  name

  60     0     999424 mmcda
  60     1     999392 mmcda1
  60     0     999424 mmcda
  60     1     999392 mmcda1
  60     0     999424 mmcda
.....

Into infinity...  this is a kernel bug...  

I'm not a kernel developer so I hacked a fix into the /etc/sdcontrol script instead....

At line 104 of /etc/sdcontrol edit as follows:

Code: [Select]

       # Read available partitions from /proc/partitions.
        PROC_PARTITIONS=`cat /proc/partitions | head -$(expr $(cat /proc/partitions | head -10 | grep -n " 0 " | head -2 | tail -1 |  cut -d: -f1) - 1)`
        # OK_PARTS="`cat /proc/partitions |awk '{print $4}'| grep mmcd`"
        OK_PARTS="`echo $PROC_PARTITIONS |awk '{print $4}'| grep mmcd`"

        echo $PROC_PARTITIONS |awk '{print $4}'| grep mmcd > "$LOGFILE-part"
Cheers,

Do you know that posting bugfixes to forum does not gwarant that it will be in next OZ releases? We have bugtracker for distro bugs.

Yes, however this bugfix should not be in the next OZ release...  It's not the right level to be addressing the problem as there are other areas of the distro that may depend on the kernel's behaviour being non-buggy.

Work-around applied with modifications:

Code: [Select]

    OK_PARTS=` head -20 /proc/partitions |grep mmcda | sort| uniq | awk '{print $4}'`
  
    echo $OK_PARTS > "$LOGFILE-part"
Thanks!
