I suudenly came up with a problem concerning mount/umount. When a mount fails, it leaves a file /etc/mtab~ and with this it prevents any other mount/umount command to run at all. As I understand this is a kind of semaphore to avoid multiple mounts to run the same time, at least in normal use. But when I get something like "Device Busy..." or so, I find out that, e.g. I didn't put a floppy to the drive or a typo, and try again, then mount fails because of /etc/mtab~.

Date: 26 Sep 1994 13:19:39 -0500 Hi, I've been watching these discussions about ELF vs a.out with quite a bit of interest. It looks, at least to me, like things will be moving toward ELF. Who actually decides if this happens and if so when it happens? What does Linus have to say about it? If this does take place, does this mean that EVERYTHING must be recompiled for ELF? (I understand that both formats will be supported, but, if we're moving to ELF then I, personally, would want to use the 'preferred' medium) Just how big is this project going to be if its implemented? It'd be nice if the hard work that all the developers have done didn't have to be recompiled or rewritten.

Thanks to all people who replied. Actually I am very sure of the software installation; due to the previous experiences, I'm used to recompile the ftape module after EVERY kernel change. I confirm that all worked fine with the 33-MHz CPU, no matter which compiler/library I used. Here are the news: now ftape works also with my 66-MHz CPU. I suspect there is some critical timing parameter on my hardware (motherboard, chipset, RAM, FD controller?), which is exposed by the faster CPU. You can't be sure of these cheap Taiwan boards, even if they are officially certified for 50 MHz operation. The quality of the crashes seemed to suggest some disruption of the instruction flow, maybe a wrong memory read. I wonder why only the ftape module was affected. Now for the solution: After fiddling with the bus/RAM/cache parameters via the BIOS setup with no success, I changed all references to inb() and outb() in the file 'fdc-io.c' to inb_p() and outb_p(), so to slow down I/O accesses via software.
