Probably 79a bad disk pack. 80.It "rl%d: header CRC" 81The controller detected a CRC error on header data read from the disk. 82Probably a bad disk pack. 83.It "rl%d: data late" 84The controller was not able to transfer data over the bus fast enough to 85not overflow/underflow the internal FIFO, probably because a heavily 86loaded Unibus or mis-ordered Unibus devices. 87.It "rl%d: header not found" 88The requested sector was not found before the timer expired. If this error 89is the only error then it may indicate a software bug. 90.It "rl%d: non-existent memory" 91The controller tried to do DMA to/from a non-mapped address. This is a 92software bug. 93.It "rl%d: memory parity error" 94The host memory data sent had a parity error. This is a hardware failure. 95.El 96.Sh SEE ALSO 97.Xr hp 4 , 98.Xr uda 4 , 99.Xr up 4 , 100.Xr syslogd 8 101.Sh HISTORY 102The 103.Nm 104driver has been around nearly forever. 105.br 106A complete new 107.Nm 108driver showed up in 109.Nx 1.5 . 110.Sh BUGS 111Error handling is less than optimal. 112.Pp 113Seeks should be interleaved between multiple disks. 114
