[1.] Kernel bug erasing a file in an ext3 fs on a usb pen

[2.]
  0) Disk partitioned with one primary partition, taking all space.
disk size is 64Mb
[cfdisk 2.11n
Copyright (C) 1994-2000 Kevin E. Martin & aeb]
  1) I created a filesystem : mkfs.ext3 /dev/sda1
[mke2fs 1.27 (8-Mar-2002)]
  2) I copied a 27 MB long file twice on the pen (two versions of the 
same file, with the same name), and got a series of "ext3_new_block: 
Allocating block in system zone" errors (see log)
  3) I tried to delete the same file, and got a "Kernel bug" message 
(see log)
