Marcelo,
While working with smartmontools I found that an
extended foreground self-test failed because the
SCSI command that sends it: SEND DIAGNOSTIC, has a
normal timeout value of 10 seconds. With my 18 GB
disk this test takes 12 minutes. Larger disks can
take up to an hour.
This patch makes the SCSI_IOCTL_SEND_COMMAND ioctl's
timeout for SEND DIAGNOSTIC the same as it is for
FORMAT (2 hours).
The scsi_ioctl.c file is the same in lk 2.4.20 and
lk 2.4.21-pre6 .
