BTW, I have posted very similar issue in the link:

Artem, I noticed from bugzillar that the hardware is i386, just
wondering if PAE is enabled?  If yes, I am more confident
that both the two kinds of report are similar or same.


Yes, I'm on i686 with PAE (16GB of RAM here) - it's specifically mentioned
in the corresponding bug report.

OK, could you dump value of the following files under /sys/block/sdN/queue/ ?

            max_hw_sectors_kb
            max_sectors_kb
            max_segments
            max_segment_size

'sdN' is the faulted disk name.


# cat /sys/block/sda/queue/{max_hw_sectors_kb,max_sectors_kb,max_segments,max_segment_size}
