Subject: Issue with firewire from 2.6.35.9 to 2.6.36.1

Hello,
I recently upgraded from 26.35.9 to 2.6.36.1 and now the /dev/fwX
devices are not being created. I have udev 164 installed.
2.6.35.9 dmesg firewire lines...
firewire_ohci 0000:07:00.0: PCI INT A -> GSI 44 (level, low) -> IRQ 44
firewire_ohci 0000:07:00.0: setting latency timer to 64
firewire_ohci: Added fw-ohci device 0000:07:00.0, OHCI v1.10, 4 IR + 8 IT contexts, quirks 0x1
firewire_core: created device fw0: GUID 0010dc0001adc862, S400
firewire_core: created device fw1: GUID 00808803072803a5, S100
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
2.6.36.1 dmesg firewire lines...
firewire_ohci 0000:07:00.0: PCI INT A -> GSI 44 (level, low) -> IRQ 44
firewire_ohci 0000:07:00.0: setting latency timer to 64
firewire_ohci 0000:07:00.0: irq 75 for MSI/MSI-X
firewire_ohci: Added fw-ohci device 0000:07:00.0, OHCI v1.10, 4 IR + 8 IT contexts, quirks 0x1
I have compared the difference between the two kernel configs and the
only differences that I see that may apply to the firewire are:
CONFIG_DNOTIFY=y
-CONFIG_INOTIFY=y
CONFIG_INOTIFY_USER=y
# CONFIG_IEEE1394 is not set
+CONFIG_FIREWIRE_NOSY=m
CONFIG_I2O=m
On the ieee1394 wiki page it says that these kernel option are expected
to be on for the libraw1394:
CONFIG_INOTIFY=y
CONFIG_INOTIFY_USER=y
CONFIG_EPOLL=y
These option are correct in the 2.6.35.9 kernel but the CONFIG_INOTIFY
option is missing completely in the 2.6.36.1 kernel.
Is this a change in how the firewire works in the kernel and that udev
needs to be modified or is there something else wrong?
