Date: Mon, 11 Dec 1995 12:38:19 GMT I am attempting to use the "cdda2wav" program to read digital audio data directly from my Plextor SCSI CD-ROM. In order to do this, I need to read from the CD-ROM as a "generic SCSI" device, i.e. /dev/sg0 or /dev/sg1. I also have a SCSI hard disk. Both the hard disk and CD-ROM are accessable after booting, the SCSI drive gets automatically mounted, and the CD-ROM can be manually mounted. However, I created the various /dev/sg devices (with 'mknod /dev/sg0 b 21 0', 'mknod /dev/sg1 b 21 1', etc.), but they are always "not accessable", when cdda2wav tries to open them.

No. But as long as there's source code available (namely for the kernel) and someone is root (we agree that someone must be root, right?) you cannot expect the kernel to contain secure structures and stuff.

Perhaps you do not notice parity errors, because linux hides them (one possible flag of misfunction of memory is getting signal 11 when compiling kernel). I had two banks of 16MB memory modules with different timings (70 & 60 ns). When I booted doze, they closed themselves after a while (~20 secs). Under linux, I could notice the misfunction only when running X or compiling. The behaviour is(may be) that when memory corruption occurs, some instruction within a process jumps to a nonexistent address (addr which is not mapped).This is treated as an attack against system and therefore the process is closed. BTW, I had to add some waitstates.....until I got two the same 16MB modules > >how can this be? are the simm chips i got smart enough to >know that fathers shouldnt permit their children to do DOS? >that's what i'd prefer but he does need dos for some things.. > > thomas > >-- >Thomas Dunbar 540 231-3938 (fax 3714) http://gserver.grads.vt.edu/ What becomes lethal for dos, doesn't have to be for linux.

It happens that, in some systems, the udelay() (as well as the BogoMips calculation) is completelly broken (causing the driver to malfunction). An easy way to identify these systems is to look at the BogoMips index. Pentiums (which should have a BogoMips around 60, shows 2 or 3). Normally, going to the BIOS setup and setting the cache mode to "write thru" instead of the default "write-back" fixes the problem. Right now, I have a customer having problem with an AMD 486-120 MHz motherboard. His BogoMips is 2.5. The Cyclades driver fails at the HW initialization (because udealy is broken). In this case, changing the cache mode did not fix the problem. It only worked when we completelly disabled the internal cache. Strangelly, the problem doesn't happen in an AMD486-80 MHz (the only difference between the two processors other than the clock is the size of the cache: 8k in the 80 and 16k in the 120). Does anyone have a suggestion on how to workaround this problem without disabling the cache completelly? Does anyone know why BogoMips (and all the related timing functions in the kernel) fails in several machines?
