New: Slow boot with dc395x compiled into the kernel.
https://bugzilla.kernel.org/show_bug.cgi?id=36822
Summary: Slow boot with dc395x compiled into the kernel.
Product: SCSI Drivers
Version: 2.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: DC395X
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
I'm using a Tekram TRM-S1040 Card with a HP Scanner connected to it. When I compile the driver directly into the kernel the kernel needs about 7 secounds to boot with a noticabe delay here:
[ 3.107686] scsi 7:0:0:3: Direct-Access Generic USB MS Reader 1.03 PQ: 0 ANSI: 0 [ 6.130981] scsi 0:0:0:0: Attached scsi generic sg0 type 3
(where sg0 is the scanner)
Also my internal drives correlate with the USB Card-Reader, so my drives are:
sda: card reader
sdb: fist harddrive
sdc-sde: card reader
sdf: secound harddrive
But if I compile the driver as a Module (so it's loaded by udev) the kernel boot time is only about 2.5 secounds, my drives are:
sda: first or secound harddrive
sdb: first or secound harddrive
sdc-sdf: card reader
also the boot-time of the whole machine (kernel + init) is reduced by around 6 to 8 secounds.
