Description
As of revision head,236, if I create a disk image on tmpfs, create a FAT filesystem on it, mount it and create a file, it crashes. To reproduce, follow these steps:
# mkfile --size 2m /scratch/img # file_bd /scratch/img bd/fdev0 # mkfat bd/fdev0 # mkdir /fat # mount fat /fat bd/fdev0 # mkfile --size 32k /fat/test
The command appears to be hung, in klog we can see that Thread 0x80083000 crashed at 0x1af76 (_heap+0x7f76). FP = 0x80028438. The stack trace appears to be bogus:
0x80028438: 0x1af76 (_heap+0x7f76) Warning: udebug_mem_read() failed.
