Public bug reported:
Binary package hint: linux-image-2.6.24-19-generic
Yesterday my desktop running Ubuntu Hardy (x86_64) started showing boot
problems: showing a blank screen (with blinking cursor) or showing the
boot splash going forward & backward, with the disk silent, not
progressing until I get bored and reboot.
When I boot in rescue mode, I see the following errors (just after it
correctly detects my hard drive on ata1):
[ 28.820922] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 28.824248] ata1.00: ATA-7: SAMSUNG SP2004C, VM100-50, max UDMA7

[ 114.409260] ata2: failed to recover some devices, retrying in 5 secs
and then it starts repeating, with longer timeouts. This goes on for 10
minutes, in the middle of which I get an (initramfs) prompt because
/dev/disk/by-id/$UUID doesn't exist.
When the 10 minutes pass, I see
[ 356.102791] ata2: classfication failed, assuming ATA
[ 356.102837] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 310)

then my hard disk becomes visible in /dev, and I can press Ctrl+D to
continue booting.
This does not happen if I boot the older 2.6.22-14-generic kernel
(version 2.6.22-14.47). (What happens is my X become unhappy because I
didn't have nvidia's binary blob installed for that kernel).
/var/log/dpkg.log tells me I got 2.6.24-19-generic (version
2.6.24-19.34) on June 26. /var/log/kern.log tells me that I
successfully booted this kernel on June 26 (several times), 27 and 28.
The first boot problems appeared only yesterday. Since then I've been
having boot problems every day. Reinstalling the kernel didn't help.
As far as I can tell, ata1 has my SATA hard disk, while ata2 is supposed
to have my DVD drive (which also has problems working in Windows).
They're both attached to a JMicron RAID controller (that had problems
loading GRUB until I reflashed it with a newer firmware).

(sda through sdd represent the multi-format card reader attached through
USB)
The DVD drive seems to work (i.e. "eject" opens the tray) despite the
long pause.
I searched on launchpad and while I found some similar-looking bugs,
none of them mentioned ata classification errors. Not being sure, I'm
filing a new bug.
