Bug Description

Binary package hint: udev

When looking for the firmware version of my hard disk (/dev/sda), I found out the last two characters reported by udevadm are inverted:

$ udevadm info --name=/dev/sda --query=property | grep ID_REVISION

I believe the above information is also used by palimpsest, see:

This is very inconvenient when trying to determine if such a disk needs a firmware upgrade on a headless system.

dmesg, however, has the right information:
magicfab@winston:~$ dmesg | grep ATA-7
[ 2.902938] ata3.00: ATA-7: INTEL SSDSA2M040G2GC, 2CV102HD, max UDMA/133

I checked this on several systems and got the same inconsistent information. I haven't checked dmegs output from a live CD to see if it would include the fixed HD information, though.

I've filed a separate bug about lshw reporting only part of such information, Bug #663349.

The fwrev size should be 8 not 6.
However, the upstream already fixed it.
