XFS internal error

[Gerardo Exequiel Pozzi <djgeray2k@yahoo.com.ar>]

Hi,

(sorry for my english)
(please cc to my email i am not suscribe to this list)
Linux version 2.6.17.11 (root@djgera) (gcc version 3.4.6) #1 PREEMPT Thu 
Aug 24 00:27:47 ART 2006
and previusly used, .7 .6 .2, and .16.X ...

This problem can be related with previus kernels that write on fs, and 
now when delete files apears the errors?

I delete a big tree directory with many files (39G) from my filesystem,
then appears this error:

djgera@djgera:/mnt/sdb1$ time rm -rf frugalware
rm: cannot remove 
`frugalware/frugalware-stable/extra/frugalware-x86_64/gnet-2.0.7-1-x86_64.fpm':

rm: cannot lstat 
`frugalware/frugalware-stable/extra/frugalware-x86_64/firefox-hu-1.5-2-x86_64.fpm': 
Input/output error

user    0m0.059s

the dmesg shows:
