Sorry, I met well a problem of unaligne access problem with fsck.jfs (wit=
h
kernel 2.4.19-pa24+jfs 1.0.23 support):
...
fsck.jfs(6995): unaligned access to 0xfaf00757 at ip=3D0x0002ee1b
fsck.jfs(6995): unaligned access to 0xfaf00757 at ip=3D0x0002ee37
fsck.jfs(6995): unaligned access to 0xfaf00757 at ip=3D0x0002ed3f
...

which occurs in fsckmsgs.c for ip=3D0x0002ee1b (for exapmple) at:

        strncpy(prlimit, msgprms[prmidx], prmval[prmidx]);
with 
...
extern char *msgprms[];
...
   int prmidx;
...    
   int16_t *prmval;

So it is not related with the struct problem I encounter.

I will try to find back this example.

PS:  with ext3 (which I use) problem I hesitate to install 2.4.20 and wai=
ting
for 2.4.21 and evms, jfs, xfs support for this system)
