jffs2_do_reserve_space

["Mike Schumi" <schumi@techie.com>]

Hi, 

  I've looked for a solution to this problem, but haven't seen it posted anywhere, although some ppl have had it before. 

 I'm running on a ARM board with 2 partitions, a Firmware Partition with the board Bootloader, Blob and Kernel 2.4.7, and another partition with the file system jffs2.
When I try to write to the jffs2 I get the below dump.
I've noticed that I this dump happens a boot after I run cardmgr to mount the /dev/hda for a ATA card.(its doesn't happen with te PCNET card)
i.e. I bootup, all is fine and do a lot of writes. Then I run cardmgr, plug in the card... mount /dev/hda on /mnt/ide ...copy files from the card, and to the card, then reboot and here is where the writes start going crazy. Any help would be appreciated ...
