Subject: 2.6.18-rc strange hotplug/udev/uevent problem
Date: Mon, 07 Aug 2006 20:33:08 +0100 [thread overview]
Message-ID: <44D79574.8080703@digital-domain.net> (raw)
Hi,
Got a weird problem here.
On x86 Fedora Core 5 with 2.6.17 with GNOME, plugging in a usb stick
would result in it being mounted. With 2.6.18-rc this no longer occurs.
FC5 got an update to hal to work with 2.6.18 kernels, but it don't work
for me. I'm having the same problem on 3 x86 FC5 machines.
The weird thing is, this all works on my x86-64 FC5 workstation with
2.6.18-rc both before and after the hal update.
Anyway I submitted a bug report against HAL suspecting it broken
https://bugs.freedesktop.org/show_bug.cgi?id=7756
Perhaps not. So I turn my attention more to the kernel.
2.6.17 was working fine. You could plug/unplug/plug a USB memory stick
and it would get mounted each time.
2.6.18-rc[23] works the same as above on my x86-64 FC5 box.
2.6.18-rc[23] and 2.6.18-rc3-git7 on x86 built with
usb/scsi/sd/vfat/nls_* built as modules will mount on the first plug but
not subsequent plugs.
If you rmmod the sd_mod module and plug in, then it will get mounted.
When the kernel is built non-modular then plugging in will not mount it.
If you boot with the device plugged in then when you log into GNOME it
will be mounted. But subsequent unmount/plug ins will not get it mounted.
The following is from the udevmonitor program running under 2.6.18-rc
built modular.
Plugging device in with sd_mod not loaded.

No mount events here, this is similar output to the non-modular case..

I guess the next thing is to try and narrow down when this started, but
as that could take some time, I'm posting this now.
