Dear developers,

i get an error using 2.1.107UP with scsi,scsi-generic and aha152x
(AVA 1502E) compiled into the kernel. 
If the scanner (Microtek ScanMaker 600 GS, id 1) is
switched on during boot, I get an error and the boot hangs. On 2.1.105
and 2.0.33 this does not happen. The error message:

scsi0: channel 0 target 1 lun 1 request sense failed, performing reset.
SCSI bus is being reset for host 0, channel 0
scsi: aborting command due to timeout:
pid 4,scsi 0, channel 0, id 1, lun1 0x03 20 00 00 10 00
aha152x:abort(), SC pnt=0xc008f400, QUEUESTATUS:

OFFCNT(0);SSTAT4();DMACNTRL0(16BIT PIO READ);DMASTAT(DFIFOEMP)

enabled interrupts
command not found

This is copied by hand and possibly not fully accurate.
i cannot contact the aha152x maintainer.
