This message announces the availability of patch level 4 of version 0.07 of Linux/68k. It can be ftped from directory /pub/linux/680x0 at tsx-11.mit.edu. A precompiled kernel executable can be found in vmlinux-0.07pl4.gz in the "kernel" subdirectory. The "bootstrap" program from 0.07pl3 should be used to boot the new kernel. The patch for the kernel source can be found in linux-0.07pl4.diffs.gz in the "src" subdirectory. The changes in this release against 0.07pl3 include: *) The NetBSD-based WD33C93 SCSI drivers for A3000, A2091 and GVP Series II have been removed and replaced with new drivers which were written from scratch, and which fit more properly into the Linux block I/O and SCSI architecture. Hopefully people will not see unexplained SCSI "hangs" with these new drivers (I don't). Note: These new drivers do not yet do anything with synchronous SCSI, or synchronous SCSI negotiation, so you must ensure that your SCSI disk drives are not using sychronous data transfers when you boot the kernel. If you have an A3000, this means you should use the "SCSIPrefs" program to ensure that the "synchronous SCSI" bit in the battmem preferences is turned off. For A2091 and GVP Series II owners, check your reference manual. Synchronous SCSI support will be added to these drivers at some time in the future.
