Tekram host adapter not recognized

[ferp2]

Hello,

I have a Tekram DC-390 U2 B/W scsi host adapter (with 3 scsi disk attached) that is not getting recognized while booting with the Gentoo 2005.1 minimal install CD. I've tried different boot options which have either not changed anything or caused the boot to fail.

Doing an lsmod after booting with the 2005.1 minimal install CD, I see the "sym53c8xx" scsi host adapter module loaded, which is the wrong one. The "tmscsim" scsi host adapter should be loaded instead. When I do a modprobe tmscsim, the module gets loaded but the virtual console becomes unresponsive. No amount of kill process_num removes it.

What I've noticed is that the drive is successfully loaded when booting with the 2.4 kernel. This is the case with an older Knoppix version. It too, however, uses the "sym53c8xx" module and there's no sign of the "tmscsim" module. A lspci shows another host adapter name. In other words not Tekram.

I'm at a lost to explain this problem. Maybe someone could suggest the correct boot options to get this working. I've tried linux noscsi which caused a kernel panic.

I've also tried booting the netinstall disk for Debian Sarge using linux26. In other words specifying the 2.6 kernel. This ha failed. I've also tried with the latest Knoppix version (booting the 2.6 kernel) and this has failed too.

Thanks

does the card work with the sym53c8xx driver loaded? if so, go with it. if you're sure it absolutely has to be the tmscsim driver instead, make sure you 'rmmod' the sym53c8xx driver first before 'moprobe'-ing the 'tmscim' driver.

best of luck,

The fact that it works with the sym53c8xx driver and not the other one should be a pretty good indication of which is the correct driver to use. The DC-390U3W in my server box runs on sym53c8xx, though I realize it is not the same exact card. lspci won't say anything about Tekram, just the chipset that it is based on. For example, from mine:
