I observe similar symptoms on my Sony Vaio notebook. I installed every version of Ubuntu since 6.x. Now I upgraded to Karmic using update- manager and booting got at least two minutes longer, or maybe more.
As far as I understand, the reason in my case is the following: - the notebook has one bay in which either DVD drive device or a floppy drive device can be inserted. - I keep DVD drive in the bay - during booting, the BIOS reports the existence of the floppy - something in Ubuntu recognizes that floppy as a device exists and wants to access it - that same thing doesn't want to let booting continue before the floppy answers! - floppy never answers. $ tail syslog Aug 6 00:00:15 mu3 ntfs-3g[3011]: Mount options: rw,nosuid,nodev,uhelper=devkit,silent,allow_other,nonempty,default_permissions,relatime,fsname=/dev/sda1,blkdev,blksize=4096 Aug 6 00:00:23 mu3 ntfs-3g[3011]: Unmounting /dev/sda1 (DRV4_VOL1) Aug 6 00:02:57 mu3 kernel: [ 187.104030] eth0: no IPv6 routers present Aug 6 00:02:57 mu3 kernel: [ 236.668071] Clocksource tsc unstable (delta = -102510018 ns) Aug 6 00:02:57 mu3 kernel: [ 259.875599] end_request: I/O error, dev fd0, sector 0 Aug 6 00:02:57 mu3 kernel: [ 298.075393] end_request: I/O error, dev fd0, sector 0 Aug 6 00:02:57 mu3 kernel: [ 298.075425] Buffer I/O error on device fd0, logical block 0 Aug 6 00:02:57 mu3 kernel: [ 336.267437] end_request: I/O error, dev fd0, sector 0 Aug 6 00:02:57 mu3 kernel: [ 336.267469] Buffer I/O error on device fd0, logical block 0 Aug 6 00:02:57 mu3 kernel: [ 374.459417] end_request: I/O error, dev fd0, sector 0 -- Karmic slow boot https://bugs.launchpad.net/bugs/405270 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
