Date: Mon, 07 Aug 2006 20:33:08 +0100 From: Andrew Clayton <andrew@...ital-domain.net> To: linux-kernel@...r.kernel.org CC: Andrew Clayton <andrew@...ital-domain.net> Subject: 2.6.18-rc strange hotplug/udev/uevent problem 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.
