Vim started crashing on me, particularly when I tried to open new lines.I think I'd run 'badblocks' on the disk.
I finally checked it out with rpm and a newly downloaded copy of vim's
rpm and discovered that exactly one byte, deep into vim, was wrong.
I rebooted my machine (which has been super-solid for years) - and the
difference was gone.
So, what are the opinions - did I run into a hardware glich, or was
there a freaky issue with memory mapping?
Hmmm. Do you mean that there might be a (intermittent) bad spot on the
disk? Would badblocks find that?
It would, but my guess is that there isn't.
A bad block will fail typically great chunks of data, and show a disk error.
Not set one byte high.
Thats typically something to do with DMA xfer, except I THOUGHT they were 16 bit or more wide these days.
