Since kernel >2.1.107, i.e. ncr53c8xx-3.0e, linux does no longer boot on this machine:
- IBM DCHS39100-UW, 9GB hard disk, id 1, autostart active, active termination, parity + TISN active | 25cm uw/68pin ribbon-cable - SYM8751SP scsi adapter | 31cm 50pin ribbon - toshiba XM-3401B cd-rom, id 4, no term, parity enabled, Burst: 4.2MBytes/sec(sync), 1.5MB/s(async) | 35 cm - IBM DFHS34320, 4.5GB hard disk, id 0, autostart, active termination, parity + TISN active
This works pretty well since 14 months, up to kernel 2.1.107.
Newer kernels give
> ncr53c875-0-<0,0>: M_REJECT received (75:8).
Last .config for 2.1.119 says:
> CONFIG_SCSI_NCR53C8XX=y > CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS=1 > CONFIG_SCSI_NCR53C8XX_MAX_TAGS=4 > CONFIG_SCSI_NCR53C8XX_SYNC=0 > # CONFIG_SCSI_NCR53C8XX_PROFILE is not set > # CONFIG_SCSI_NCR53C8XX_IOMAPPED is not set
There is no (scsi) error when i disconnect the XM-3401B cd-rom.
There is no error, as long as the XM-3401B is disconnected, when i add both a HP 35480A dat drive (typ: 366-732kB/sec), id 3 and a fujitsu m2511a MO disk drive (Burst: 4.0MB/sec/sync, 2.7MB/s/async), id 2.
I may even reduce cabling distance to 10cm, with 170cm total length and use passive termination at the scsi II end without getting errors for 2.1.11[79], as long as the cd-rom is not connected.
Any hints (besides discarding that outdated 2.2 speed caddy needing cd-rom drive)?
