Should be fixed in kernel-2.6.29.1-77.fc11 build 70 or 77. I only see as high as 70 in rawhide/koji OK, I don't see the kernel oops anymore but I don't see any file systems either.

Earlier kernel-2.6.29.1-70.fc11.i586 worked ok but unfortunately I can't find it from mirrors anymore and can't verify that it really was the kernel upgrade that caused this regression. Nokia E75 can be connected in 5 different modes over USB and with kernel-2.6.29.1-70 two of the modes provided access to storage area on the phone, one to memory card and one to a "CD-ROM" drive. Now both of these are showing without partitions. In camera mode photos can be still accessed, though. Below are syslog output, first with USB Mass Storage mode and second in CD-ROM mode.

I have narrowed this down to DeviceKit-disks upgrade, please see https://bugzilla.redhat.com/show_bug.cgi?id=496683 I am still wondering how non-kernel upgrade can mess up disk partition visibility. PS. I think the original issue this bug was created for is now clearly solved and this report should be closed. I see that https://bugzilla.redhat.com/show_bug.cgi?id=495876 is also related. I think it is now clear that the missing partitions are due to a udev issue, please see Bug 496683. I think this bug can be closed if the oops is gone. |
