Subject: [9fans] New venti install won't boot after 05:00 crash
Date: Fri, 18 Mar 2011 16:47:37 +0000 [thread overview]
Message-ID: <20110318164944.4197965D3E@server.hemiola.co.uk> (raw)

I have seen similar symptoms. In the end, I narrowed my problems down
to a very particular combination of hard drive and laptop.
The installation would complete fine, but I would get i/o errors
running plan9 from the (pata) hard disk. I tried with and without dma
and rwm. "dd" read and write tests run from the installation disk all
proved to be ok. Stand-alone hard disk and memory diagnostics didn't
show up any hardware errors. Another hard drive worked fine with the
same laptop and, bizzarely, the hard drive worked fine with plan9 in a
different laptop. Debian and windows installed and ran fine.
Interestingly, I had another laptop of the same model (inspiron 3500)
which also failed identically.
I concluded that there was most likely something about the timing in
the ata driver that tickled the drive/interface combination.
