Upgrade to Ubuntu 7.04

Yesterday, I follow the instruction here to upgrade my Ubuntu to 7.04. Unfortunately, the Update Manager crashes during package installation. To solve the problem, I use the following command:

dpkg --configure -a

Then, I reboot the Linux box. Some errors occurs. It fails to mount all partitions, excepts "/" partition. After some investigation, under the new kernel (2.6.20), IDE harddisks/CD-ROM are considered as SCSI. The following is the dmesg output:

ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x0001f000 irq 14
ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x0001f008 irq 15

Therefore, the entries in /etc/fstab should be changed from "/dev/hdan" to "/dev/sdan".
