[bug kernel 2.6 / USB / SCSI] report

[Daniel Moyne]

Here is my bug report :

a) data of my system

Linux azun.home.fr 2.6.3-4mdk #1 Tue Mar 2 07:26:13 CET 2004 i686 unknown 
unknown GNU/Linux

Gnu C                  3.3.2

supermount via-agp agpgart ppa parport_pc imm parport usblp ehci-hcd uhci-hcd 
usbcore rtc ext3 jbd sd_mod dc395x scsi_mod

Other :
distribution : MDK 10.0 Community kernel 2.6.3-4mdk
Motherboard : MSI K7T Turbo 2 with CPU AMD Duron 1 GHz

b) problems :
2.4.x works fine.
2.6.x is much faster but shows some problems with USB and SCSI drives.

USB :

- the only way to get my USB printer recognized is to use the following 
modules (from lsmod) :
usblp                  12256  0
ehci-hcd               24196  0
uhci-hcd               29104  0
usbcore                99132  6 hid,usblp,ehci-hcd,uhci-hcd

and set the following "append" option in lilo :
	append="devfs=mount noapic resume=/dev/hda5"
what is relevant here is obviously the "noapic" option ("apic=ht" works fine 
for kernel 2.4.x)

- ohci does not work !

SCSI / CD drives :

- following some recommandations I removed the SCSI IDE mulation from both 
"lilo.conf" and "modules.conf" files.

- both K3b and XCDroast cannot locate my SCSI CD drives : K3b gets stuck from 
the very beginning when searching CD devices and XCDroast finds my IDE drive 
but then gets stuck also.

- GCombust works fine

I am willing to answer your questions to pursue diagnosing the various 
problems.
Regards.

Ok, there's no problem there.

Do you have OHCI hardware?  If not, why would you expect it to work?
