Cold booting into archlinux

[mores]

There seems to be a common issue that a cold boot ( toggle power ) will boot into factory OS while a warm boot ( reboot ) will start archlinux just fine.

I have seen many different attempts to fix it:
- change bootcmd
- change usb_rootdelay
- try a different flash drive
- try a different port
- use a smaller working flash just for kernel
- in factoryOS check /etc/init.d/rcS
$this->bbcode_second_pass_code('', '
checkusb=`grep sda /proc/partitions`
if [ -n "$checkusb" ]; then
/sbin/reboot
fi
')

Has a consensus been reached on the correct way to fix the issue ?
Has a consensus been reached on what the real issue is ?

Have enough people had this problem that it deserves to get put on the FAQ ?

Generally the problem stemmed from the amount of time it took to power on the drive that holds the rootfs. Or if other drives or devices are plugged in and seen first (thus loaded as /dev/sda) then the plug won't boot at all. My old drive would power on slower than the connection to my USB printer, so I would have to disconnect the printer first while in the reboot process and then reconnect/start CUPS/start Samba. Since changing drives I've had no issues. Changing the rootdelay was the solution of choice for a while (still is?). According to the devs for the pogos the best port is right above the ethernet port. Should all else fail having the drive connected to the internal sata (for pro only, if I'm not mistaken) is a sure thing. The code you posted could work, but if the timing of the power-up-state is just right, your plug will reboot forever

Which hardware/plug are you using that is causing issues?

I am using a POGO-E02.
The only usb device currently plugged in is a brand new Toshiba 4GB TransMemory U2K USB Flash Drive.
It is plugged into the usb port directly above the ethernet port.

So far I have changed usb_rootdelay from 10 to 15.

My next step will try to increas usb_rootdelay to 20, if that does not work I will be configuring a netconsole so I will be able to see more detail.

Increasing usb_rootdelay to 20 did not help. Here are the cold boot logs:

My solution was to use a different flash drive.

warm boots only:
[ 6.507271] scsi 0:0:0:0: Direct-Access TOSHIBA TransMemory PMAP PQ: 0 ANSI: 0 CCS


cold and warm boot:
[ 6.914148] scsi 0:0:0:0: Direct-Access SanDisk Cruzer Blade 8.02 PQ: 0 ANSI: 0 CCS
