Bug 17762 – ide-scsi emulation doesn't work in gentoo-sources 2.4.20-r1

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Manfred Stienstra 2003-03-18 12:46:32 UTC]

When I upgraded gentoo-sources 2.4.19 to 2.4.20-r1 ide-scsi stopped working. I
have found a post on the forum by someone who has te same problem. I think this
is a bug.

I have attached my kernel config.

Reproducible: Didn't try
Steps to Reproduce:
1. emerge gentoo-sources
2. cd /usr/src/linux; make dep && make bzImage modules modules_install
3. install the kernel

linux kernel config

[Comment 2 Narada Sage 2003-03-18 14:06:28 UTC]

I had hdd=ide-scsi appended to my kernel boot line in grub.conf and had ide-cdrom and all scsi items compiled into kernel with the exception of scsi disk support.  However, whereas before cdrecord -scanbus would work perfectly more recently having switched to gentoo-sources-2.4.20-r1 the same command cannot recognise the scsi driver.  I'm told that if you have both scsi-items and ide-cdrom compiled in whichever loads first takes over.  So to get around this problem I made ide-cdrom a module and modified the boot parameter to hdd=scsi.  This seems to have solved the issue but the issue of the kernel still remains.  My kernel configuration can be found on http://dhruba.codewordt.co.uk/info/kernelconfig.txt in the near future.

[Comment 3 Manfred Stienstra 2003-03-22 12:33:52 UTC]

Like you implied, leaving out ide-cdrom seems to cure the problem.

[Comment 4 a+gentoobugs 2003-03-24 08:59:52 UTC]

still seeing this problem with 2.4.20-r2

[Comment 5 Narada Sage 2003-03-24 09:13:51 UTC]

As mentioned in my previous message try removing ide-cdrom from kernel and changing boot parameter to hdX=scsi.  This has done the trick for most people.

[Comment 7 Karl Steddom 2003-04-25 10:27:33 UTC]

This is a bug with Gentoo-sources, it does not happen with vanilla-sources with the same kernel configs. Neither removign ide-scsi nor using hdc=scsi does not work as suggested. I spent a great deal of time working on this for both gentoo-sources and vanilla-sources. When using vanilla-sources with the ide-scsi module and using hdc=ide-scsi the drive is mapped to the scsi bus.
A thread on the forums, http://forums.gentoo.org/viewtopic.php?t=44678&highlight=idescsi, suggests that the whole boot parameter line is ignored and not just the ide-scsi portion. If this is so, then this kernel needs to be masked.

[Comment 8 Jay Pfeifer (RETIRED) 2003-05-04 14:10:17 UTC]

would you please try pfeifer-sources-2.4.20_pre9?

Thanks,

Jay

[Comment 9 Jay Pfeifer (RETIRED) 2003-05-09 16:54:24 UTC]

appears to be fixed in pfeifer-sources-2.4.20_pre8 and higher as well as gentoo-sources-2.4.20-r4.
