Hi, it seems SCSI got broken somewhere on the way from 2.6.19.7 to 2.6.20 on oldworld Apple PowerMacs 9500 using the internal mesh-controller. The kernel fails to read the partition table from the drive(s) with the following messages: | mesh_host_reset | mesh: target 0 synchronous at 10.0 MB/s | sd 0:0:0:0: scsi: Device offlined - not ready after error recovery | sd 0:0:0:0: rejecting I/O to offline device | sd 0:0:0:0: rejecting I/O to offline device | sd 0:0:0:0: rejecting I/O to offline device | sd 0:0:0:0: rejecting I/O to offline device | sda : READ CAPACITY failed. | sda : status=0, message=00, host=1, driver=00 | sda : sense not available. | sd 0:0:0:0: rejecting I/O to offline device | sda: Write Protect is off | sd 0:0:0:0: rejecting I/O to offline device | sda: asking for cache data failed | sda: assuming drive cache: write through | sd 0:0:0:0: Attached scsi disk sda (...) mesh.c and mesh.h (in drivers/scsi/) are identical between the two versions, so it seems that this is something at a different layer... Maybe it's connected to http://marc.info/?l=linux-scsi&m=117596425706527&w=2 but my test of 2.6.21-rc5 failed similarly to the test of 2.6.20. You can find kernel-config, full boot-time-output and build-logs at http://www.geweb.net/tmp/linux-kernel/ README contains the commands used (on a debian r3.1 sarge box) if you'd like to check the builds (see linux-$VERSION for precise make-calls). I can test a version between the two mentioned above if you let me know which one.
