Re: DOC 2000 driver (NFTL) in kernel 2.4.7

[Alexandru Harsanyi <a.harsanyi@willhart-tech.com>]

Hi,

I commented out the ECC checking part, and nftlmount.c now detects my
partition. I mounted it read-only and made some tests with copying some
files of it. It seems to be working.

However, when I mount it read-write and I write some files to the
partition, the NFTL driver hangs my system...

The messages are:
------------
_Doc_WaitReady called for out-of-line wait
Setting inplace to 0. VUC 194, block 2 was 0 lastEUN, and is in EUN 333
(!=) 673
Cannot fold Virtual Unit Chain 194 in place. Trying out-of-place
-------------

The DOC data doesn't seem to be corrupted (as I can boot from it again)
but nothing gets written to it.

Best Regards,
Alex.
