Hi lkml.
when i do a
fd = open( "/dev/fd0", O_WRONLY );
in 2.4.2 series kernels, i get these messages on the console:
psubash kernel: floppy0: reschedule timeout lock fdc

the last 4 lines showup after 2-3 seconds as I guess they are from the bottom halves.
To prevent this from writing all over my text based app I have to flank the open() with syslog()'s.
On a 2.2 kernel I get 2 debug lines instead (from end_request).
Are the log levels correct for these debug messages ?
Thanks,
