Tried to fix a bug http://bugzilla.kernel.org/show_bug.cgi?id=3736 which appeared between kernels 2.6.9-rc1-bk1 and 2.6.9-rc1-bk2.
Suceeded to localize it to part of changes in drivers/char/tty_io.c. I guess changes were according changelog: ----------------------------------- [EMAIL PROTECTED], 2004-08-24 12:29:18-07:00, [EMAIL PROTECTED] [PATCH] /dev/ptmx open() fixes If tty_open() fails for a normal serial device, we end up doing cleanups that should only happen for failed open of /dev/ptmx. The results are not pretty - devpts et.al. end up very confused. That's what gave problems with ptmx. This splits ptmx file_operations from the normal case and cleans up both tty_open() and (new) ptmx_open(). Survived serious beating. ----------------------------------- Finally located that a problem seems to be a simple typo ( --- linux-2.6.10/drivers/char/tty_io.c~1 2004-12-24 23:34:58.000000000 +0200 +++ linux-2.6.10/drivers/char/tty_io.c 2005-01-22 10:54:32.000000000 +0200 @@ -1148,7 +1148,7 @@ static inline void pty_line_name(struct int i = index + driver->name_base; /* ->name is initialized to "ttyp", but "tty" is expected */ sprintf(p, "%s%c%x", - driver->subtype == PTY_TYPE_SLAVE ?
