Hello,

Back in October of last year I had problems with a new kernel on my machine (Mageia 4 64 bit) which I reported here. Over the weekend, I did another upgrade to be greeted on Sunday morning by a kernel panic and it wouldn't go at all.

So rapidly getting fed up with it and even more rapidly losing what little I had left of my patience, I downloaded Mageia 5 Beta 3 and using that as a live DVD, booted up the box and did a backup of / to an attached NTFS disc. Encouraged by the fact that the live system worked and even though it's still a beta, I installed it over Mageia 4.

It works and even though it's done loads more upgrades since yesterday morning, it's still working apart from a 1TB USB disc. I wasn't seeing any notifications when I plugged it in but that was fixed by a setting on the device notifier. If I plug in a 32GB USB stick, that does pop a notification and I can see the disc in the file manager. But even though dmesg shows the 1TB disc as being present, it's not mounting.

Does anybody have any ideas why not?

Just in case it's important, I notice that when the machine boots, right at the start there's a message about /usr/lib/udev/rules/50-firmware.rules but that's empty apart from a couple of comments.
