Try : >the LSM. : I think that some models of the NeXT used flopticals, but the world wasn't : ready for them at the time. The NeXT I used to play with had a standard : 3-1/2" drive which, as you said, could handle FAT, HFS, and whatever-the- : native-NeXT-filesystem-was disks. (Is it the SAME as Berkeley's FS, or : merely similar????) Sorry. What I meant was that the "standard" drive on a NeXT was/is (?) a 2.88. You could get floptical, but it was optional/only on high-end models. From what I remember, the file system is close to, but not equivalent to, to 4.4- BSD's file system. : >chris : >-- : >Chris Ricker : gt1355b@prism.gatech.edu : The Georgia Institute o' Technology : >"I got a threshold, Jules.

Some sort of timing problem in the hardware, or maybe a broken drive. Sometimes this is due to useing a "fast" interface timing on a "slow" drive. -- mlord@bnr.ca Mark Lord BNR Ottawa,Canada 613-763-7482 For Linux IDE (big/many) help, see: /usr/src/linux/drivers/block/README.ide For latest Linux kernels: ftp.cs.helsinki.fi:/pub/Software/Linux/Kernel/v1.[23] ------------------------------ From: makisara@abies.metla.fi (Kai Makisara) Subject: Re: 1.3.30 oops Date: 30 Sep 1995 14:32:29 GMT In article Richard Waltham writes: Hi, Couple of problems I've come across running scsi tapes in kernel 1.3.30. st_options.h set up with ASYNC writes OFF and 2 FILEMARKS, all other options at the default values, tape devices HP1533a, controller aha1542cf. Typical tape command causing problem - "tar -cvf /dev/st1 -C /usr ." 1. In VARIABLE and FIXED block mode. The tape goes into an uninterruptible sleep after writing the closing filemarks. This happens using rewind or The problem is specific to writing two filemarks when closing file AND having SCSI adapter driver configured for only one outstanding command per lun. The driver tries to allocate a command for backspacing over the second filemark before releasing the command used for writing filemarks. ... 2. In FIXED mode an OOPS is generated as below, apparently somewhere in the tape_write routine, caused presumably by the NULL pointer deference. This appears to happen on the first call to tape_write and after the oops the The problem is that the SCSI command is "released" in fixed block mode even if it has not been allocated (the written data fits into the driver buffer). The same problem seems to be also in st_read. The patches at the end of this message fix the problems. Note that these problems are specific to 1.3.30 (I hope the fix will reach Linus before 1.3.31 :-) Finally a question - what is ksymoops? I've seen mention of it here and there and it looks like its something to extract the symbols from System.map for an oops automatically. Is this right and if so where can I find it? You can find ksymoops.cc in linux/scripts starting from 1.3.26. Thanks for the thorough problem report.

Why would anyone want that? This is traditionally the behaviour and was seen in SunOS 4.x and early Solaris 2.x versions. (See how dangerous it is to say "some system (Sun?)", OSes aren't cast in stone) More people felt it was broken ... >I believe on some systems there is a flag RLD_GLOBAL? that switches >this behavior. ... so Sun introduced RTLD_GLOBAL in Solaris 2.3 (I think). >Is there any chance that this might be fixed?
