Well Folks,
This one is a real mystery.....
I cannot believe that my setup is unique, but hey... stranger things can
happen I suppose. I have an Adaptec AHA-2940U2W with several devices (
see 2.0.38 dmesg out below), and an IDE primary drive where my boot
record lives with a (bootable) DOS partition as well as some other Linux
partitions:
hda: hda1 hda2 hda3 hda4 < hda5 hda6 hda7 hda8 >
hda: WDC AC26400B, 6149MB w/512kB Cache, CHS=784/255/63
My main (mother) board is an FIC PA-2013 with a 350MHz AMD K6-2
CPU, Millenium G200 video adapter, 128MB (PC100) SDRAM, sound card and
modem reside in the 2 ISA slots and a 3COM 3c905B Cyclone ethernet card
in one of the PCI slots.
(aka very typical setup??)
When booting any Linux 2.2.X kernel with this IDE drive present I get a
timeout message (which I have posted before, but will include here for
completeness):
scsi : aborting command due to timeout : pid 60, scsi0, channel 0, id 1,
lun 0 0x28 00 00 70 c2 ce 00 00 02 00
The timeout can last anywhere from 25 to 40 seconds. Another symptom is
LILO will hang (i.e. executing lilo) or take a very long time to
execute.
When I boot any of the 2.2.X kernels without this drive present the
timeout disappears. In fact when I boot with this drive present in any
of the newer 2.0.3X kernels which support this adapter there is NO
timeout and lilo behaves normally!
So why don't I just shutup and just use the 2.0.38 kernel? Well I do,
but I would like to have some of the newer 2.2.X kernel features not
present in the 2.0.3X kernels.
If anyone has a similiar hardware setup (at the very least has the
2940U2W) that mixes both scsi and ide in the 2.2.X kernels and get no
timeouts or lilo troubles, please let me know. I have discussed this at
length with Doug Ledford and I am sure he would be interested in knowing
also. It is possible that there is something in my BIOS (and/or BIOS
settings) that the 2.0.3X kernels (as well as WINDOZE :) overlooks or
doesn't care about.
TIA,
Steve
