I'm trying to upgrade my kernel from 2.6.15, but my external RAID drops ba= ck to 5 MB/s due to domain validation errors. With my current kernel 2.6.1= 5 the performance is OK. Here are the details: - kernel: 2.6.15-1-686 i686 GNU/Linux - kernel driver: sym53c8xx - 2.2.1 - hostadapter: LSI Logic / Symbios Logic 53c1010 66MHz Ultra3 SCSI (rev 0= 1) - external RAID: Transtec BR-1600U3p=20 Please note, that the hostadapter is a 66MHz/32bit device stuffed into a p= lain 33MHz/32bit socket. (I'm not sure it that matters.) With kernel 2.6.20-rc3 the following kind of error are logged while iterat= ing down to FAST-5: target0:0:0: FAST-40 WIDE SCSI 80.0 MB/s DT (25 ns, offset 31) sym0: unexpected disconnect scsi 0:0:0:0: illegal scsi phase (4/5). target0:0:0: Domain Validation detected failure, dropping back sym0:0: No MSG OUT phase after selection with ATN. sym0:0: ERROR (0:48) (8-ae-0) (1f/38/80) @ (scripta 70:9e030000). sym0: script cmd =3D 80000000 sym0: regdump: da 10 80 38 47 1f 00 0e 00 08 00 ae 80 01 06 02 00 = 3c 53$ 08 00 00 00. sym0: SCSI BUS reset detected. sym0: SCSI BUS has been reset. =20 I have tried kernels 2.6.18, 2.6.19.1 and 2.6.20-rc3. They all show the sa= me pattern. With kernel 2.6.15 no such errors are printed (see both attach= ed logfiles). Do you have any ideas how to fix this problem=3F Best Regards Andreas Heiduk =5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F Viren-Scan f=FCr Ihren PC!
