Description David Zeuthen 2007-04-30 02:18:46 UTC

When plugging in a USB harddisk, I get this

This is wrong, for

/devices/pci0000:00/0000:00:03.3/usb4/4-4/4-4.2/4-4.2:1.0 (usb)

there's no corresponding UDEV meaning that something ate the event. 

This means that pieces in the stack above udev will fail and the device won't
get mounted. Marking this as a FC7 blocker. Thanks.

Comment 1 David Zeuthen 2007-04-30 02:28:42 UTC

Downgrading to udev-106-2.fc7 fixes this... so the regression was introduced in
your last update.

Comment 2 David Zeuthen 2007-04-30 02:56:11 UTC

In 05-udev-early.rules we have this

+ ACTION=="add", SUBSYSTEM=="?*", ENV{MODALIAS}=="?*", RUN+="modprobe $env{MODALIA
S}", OPTIONS="last_rule"

Removing OPTIONS="last_rule" fixes the problem. In 106-2.fc7 the modprobe rule
was in 50-udev.rules and without last_rule. 

I wonder why you added last_rule? It means that no other rules will ever get
applied, in particular, the ones in /etc/udev/rules.d/90-hal.rules will not get
applied and that is what is causing this problem. So this should be easy to fix.
Marking bug as such. Thanks!

Harald?

Comment 5 Harald Hoyer 2007-05-02 10:03:49 UTC

hmm... ok, had another problem with usb harddisks, which required the "last_rule"

Comment 6 Harald Hoyer 2007-05-02 11:43:47 UTC

udev-106-4.fc7

Just curious, what problem was this? In general, one should never use
"last_rule" at all since there's no way of knowing what rules will follow..

Comment 8 Harald Hoyer 2007-05-02 16:00:51 UTC

ACTION=="add", SUBSYSTEM=="scsi", WAIT_FOR_SYSFS="ioerr_cnt"

was done after the modprobe, which timed out...

Comment 9 Harald Hoyer 2007-05-02 16:01:25 UTC

ACTION=="add", SUBSYSTEM=="scsi", WAIT_FOR_SYSFS="ioerr_cnt"

was done before the modprobe, which timed out...

Comment 10 Paul W. Frields 2007-05-04 14:52:49 UTC

Is 106-4.fc7 coming to a repo near us now that the merge is more or less complete?

Comment 14 Jens Knutson 2007-05-10 07:44:47 UTC

Installed the rpms from the above Koji link - this fixed the problem for me.
