USB flash device not recognized on cold boot, but on reboot

[Paul Menzel]

Dear SeaBIOS folks,

on LinuxTag 2014 the OpenMandriva project [1] gave away USB flash
storage devices with OpenMandriva installed for live booting. Testing it
out on the ASRock E350M1 with coreboot and SeaBIOS payload it was not
detected by SeaBIOS, meaning pressing F12 it was not listed in the boot
options.

Rebooting the system by pressing Ctrl + Alt + Del the USB device was
recognized by SeaBIOS and listed in the boot menu.

I am still able to reproduce this with SeaBIOS build from master. Please
find the coreboot and SeaBIOS logs attached.

Thanks,

Paul

Thanks.  At first glance this looks like it could be a quirk of the
particular flash drive.  Can you apply the patch below, set the
SeaBIOS debug level to 3, and report the results of both the
working/not-working cases?

That might be. As a side note, enabling serial console in coreboot and
SeaBIOS causes the devices to always be detected. With serial console
the boot takes longer, as the messages need to be transmitted, so it
could be a timing issue.

I forgot to lower the debug level to 3, so it is still at 8. Sorry. I
hope that is still fine. If not, I’ll redo the tests.

Thanks,

Paul

As requested in #coreboot on <irc.freenode.net> I attach the logs with
SeaBIOS built from 67fd42cf, your patch and debug level 3.

Please note that during one run, the USB storage device was even
detected on first try, so I plugged it into to a different port.

Thanks,

Paul
