There's no clever advice I could give you, but I vaguely remember having
similar problems and similar logs some time ago (perhaps when kernel
2.6.29 became stable). The block device of my drive used to become
inaccessible, but the mounted filesystem continued to work, IIRC. But
I was rapidly switching SATA and IDE devices, playing with BIOS settings
at that time and eventually (perhaps after a kernel upgrade) the
symptoms disappeared...
Are you running Linux kernel 2.6.31?
