set_param_str() cannot use kstrdup() to duplicate the parameter. That's
fine when the driver is compiled as a module but it sure is not when built
into the kernel as the kernel parameters are parsed before the kmalloc
slabs are setup.

The VM layer (on the face of it, fairly reasonably) expected that when
it does a ->writepage() call to the filesystem, it would write out the
full page at that point in time. Especially since it had earlier marked
the whole page dirty with "set_page_dirty()".
But that isn't actually the case: ->writepage() does not actually write
a page, it writes the parts of the page that have been explicitly marked
dirty before, *and* that had not got written out for other reasons since
the last time we told it they were dirty.
That last caveat is the important one.
Which _most_ of the time ends up being the whole page (since we had
called "set_page_dirty()" on the page earlier), but if the filesystem
had done any dirty flushing of its own (for example, to honor some
internal write ordering guarantees), it might end up doing only a
partial page IO (or none at all) when ->writepage() is actually called.
That is the correct thing in general (since we actually often _want_
only the known-dirty parts of the page to be written out), but the
shared dirty page handling had implicitly forgotten about these details,
and had a number of cases where it was doing just the "->writepage()"
part, without telling the low-level filesystem that the whole page might
have been re-dirtied as part of being mapped writably into user space.
Since most of the time the FS did actually write out the full page, we
didn't notice this for a loong time, and this needed some really odd
patterns to trigger. But it caused occasional corruption with rtorrent
and with the Debian "apt" database, because both use shared mmaps to
update the end result.
This fixes it. Finally. After way too much hair-pulling.

The wrong matrix was used when an external input was selected instead of
the tuner input. The rxsubchans field was also not initialized to STEREO
for an external input. And finally the msp34xxg_detect_stereo() should
not try to detect stereo for an external input, that code is for the
tuner input only.
Together these bugs made it hit 'n miss whether you ever got stereo out
of the msp3400 for an external input.

I have a system with AMCC PowerPC 405EP and PHY Intel LXT971A. Linux
2.6.18.3 is not able to detect the PHY ID correctly. The PHY ID
detected is 0, but should be 0x1d.
This is because phy_read() (__emac_mdio_read() resp.) from
drivers/net/ibm_emac/ibm_emac_core.c might return -ETIMEDOUT or
-EREMOTEIO on error. This is ignored inside the
int mii_phy_probe(struct mii_phy *phy, int address)
from drivers/net/ibm_emac/ibm_emac_phy.c
as the return value is assigned to an u32 variable.
