Hello lkml, hello linux1394-devel,
I've noticed a *very* long delay upon booting current -mm kernels.
Here's a snippet from netconsole with 2.6.17-mm6:
------------snip--------------------
[ 50.651945] ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [APC1] -> GSI 16 (level, low) -> IRQ 16
[ 50.655774] NVRM: loading NVIDIA Linux x86_64 Kernel Module 1.0-7182 Wed Apr 19 13:55:00 PDT 2006
[ 50.763074] ACPI: PCI Interrupt 0000:00:06.0[A] -> Link [APCJ] -> GSI 23 (level, high) -> IRQ 23
[ 51.078391] intel8x0_measure_ac97_clock: measured 50730 usecs
[ 51.082255] intel8x0: clocking to 46828
[ 51.651890] ohci1394: fw-host0: AT dma reset ctx=0, aborting transmission
[ 229.450216] input: USB HIDBP Keyboard 046a:0001 as /class/input/input0
[ 229.458201] usbcore: registered new driver usbkbd
[ 229.462264] drivers/usb/input/usbkbd.c: :USB HID Boot Protocol keyboard driver
[ 229.473883] input: Logitech USB-PS/2 Optical Mouse as /class/input/input1
[ 229.479629] usbcore: registered new driver usbmouse
------------snap--------------------
So, we're waiting 3 minutes from 'ohci1394: aborting transmission' until
'input: USB HIDBP' kicks in and boot continues as usual. Unfortunately
I'm not sure since when this unusual delay is present as I don't
monitor the box' startups closely. With 2.6.18-rc1 it's:
------------snip------------
[ 48.318107] intel8x0_measure_ac97_clock: measured 50655 usecs
[ 48.322011] intel8x0: clocking to 46909
[ 48.748826] ieee1394: Host added: ID:BUS[0-00:1023] GUID[0010dc00009b6e48]
[ 226.073196] input: USB HIDBP Keyboard 046a:0001 as /class/input/input0
[ 226.080945] usbcore: registered new driver usbkbd
[ 226.084830] drivers/usb/input/usbkbd.c: :USB HID Boot Protocol keyboard driver
------------snip------------
Full logs/config/lspci here: http://nerdbynature.de/bits/2.6.17-mm6/
While I'm trying to find out the first kernelversion with these
symptoms: any ideas on this one?
I can see the "[PATCH 2.6.17-rc5-mm2 00/18] ieee1394: misc updates"
patchset, maybe I'll start with this one....
Thanks,
Christian.
