The problem seems the ioctl TCSETS, with the patch (and on kernel
2.6.23) it returns immediately, and on kernel 2.6.24 (without the
patch) it goes to tty_mode_ioctl().
This patch also resolves the 'bug'. It intercepts TCSETS on
switch(cmd) and return -ENOIOCTLCMD;

No, that patch doesn't resolve the bug. That just avoids the bug. The bug
is that the driver "goes silly" when passed a TCSETS cmd, and you need to
reload the driver to make it sane again.
Aren't you curious as to why TCSETS calls are made, and why things go
wrong when they are?
