[sane-devel] Kernel panic with Mustek scanner and aha1542 scsi card

Hello,

On a debian testing up to date, I'm triying to use a Mustek Paragon 600 II
CD connected to an Adaptec aha1542.
But when I try scanimage -L I have a kernel panic. I found lot a
informations on an old bug related to buffersize and sg module. But this one
seems to be corrected for ages and every workaround described won't work for
me.
Note, this hardware was working well with a ubuntu dapper.

The kernel panic is :
Bad segment list supplied to aha1542.c (1,0)
0: c0318000 5
cptr c0342e00: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
<0>Kernel panic - not syncing: Foooooooood fight!

Is there something I'm doing wrong ? or is it a regression ? where ?

Thanks
JJL

following, details about configuration

My /etc/saned.conf/mustek.conf has thoses lines :
option strip-height 1
option disable-double-buffering
/dev/sg0
option buffersize 32

dmesg gives me :
SCSI subsystem initialized
Configuring Adaptec (SCSI-ID 7) at IO:230, IRQ 11, DMA priority 5

  Vendor: SCANNER   Model:                   Rev: 2.03

scsi 0:0:1:0: Attached scsi generic sg0 type 6
(also my tape reader is listed)

The kernel is 2.6.18-3-686, and sg module is 3.5.34

here's the debug output of scanimage :
