I have to report a possible kernel bug on version 2.3.45 about the
driver aic7xxx,
I have AHA 2940 U2W and an 18.3G WD scsi LVD and 9.1G WD LVD
the scsi controller with the disks and the bus installed on a 2.2.12
kernel linux PC
works properly (mkfs copy rm etc etc)
the same controller with the same disks and the same bus on a 2.3.45
kernel linux PC
on the boot displays this error 3 times with three differnent
sg_addresses for the 18G disk

invalid cur_addr:0x1fdffa4 during WIDE_RESIDUE
sg_address:[-1]:0x1fd15c0 sg_lenght[-1]:255
sg_address:0x0 sg_lenght:0

when trying mkfs the disk or copy or anything it "times out" i can do nothing but hard reset

i downgraded the kernel from 2.3.45 to 2.2.12 on the same PC and the 18G disk works properly

I have tried this with different motherboards differend AHA2940 with different memories/cpu/bus

i have tried this on several PCies i have tested it with different jumper setup on the disk

the conclution is the same. 2.2.12 works fine 2.3.45 does NOT work fine

Thank you for you time
