multisession on CD-RW with cdrecord

[Gerard Robin <jag.robin18@wanadoo.fr>]

hello,
with kernel-image 2.4.20, I burned a CD-RW in multisession mode.
I use mkisofs 2.0+a38-1 + cdrecord 2.0+a38-1.

My problem is that until the 19 th session all works fine, but at the 20 th
session when I eject, I mount and I do: "cd /cdrw/Debsept04; ls" I get:

Oct  4 12:44:09 mymachine kernel: scsi0: ERROR on channel 0, id 1, lun 0, CDB:
Request Sense 00 00 00 40 00

error
Oct  4 12:44:09 mymachine kernel:  I/O error: dev 0b:01, sector 1127804
 
And on 62 files (packages Debian) only 26 files are copied on the CD-RW.

"isovfy /imgISO/image2.iso" displays:

Root at extent 44d5c, 2048 bytes
[0 0]
No error found

"cdrecord -dev=1,0 -msinfo"  displays: 281920, 290135

"du -s /cdrw" displays: 283008

Is there a problem in mode multisession with cdrecord and CD-RW ?

Thanks in advance for any help.
