The problem I am facing in the driver is:
When I give
dd if=/dev/zero of=/dev/sda bs=1024 count=100
It works, if I give
dd if=/dev/zero of=/dev/sda bs=1024 count=1000 (Samething works in Kernel
2.4.18-3)
System crashes.
I am not using interrupt handler and scatter gather lists.
Here is my driver_template structure:
#define MY_SCSI \
{ \
name: DRVR_NAME, \
proc_info: myscsi_proc_info,\
bios_param:myscsi_bios_param,\
detect:myscsi_detect, \
info:myscsi_info,\
release:myscsi_release,\
command:myscsi_command,\
queuecommand:myscsi_queuecommand,\
can_queue:0, \
this_id:7,\
cmd_per_lun:1,\
sg_tablesize:SG_NONE, \
unchecked_isa_dma:0,\
highmem_io:1, \
}

Thanks n Regards,
Mohan.
