Hi,
I'm running linux 2.0.38 with libc5.4.46 and egcs v1.0.3 as the compiler.
Here are some problems I'm having with this kernel version.
Hardware:
333mhz Dell optiplex GX1
2940U2W AIC7895
Western Digital 9.1G SCSI disk
Quantum Fireball 1.2G IDE disk
3Com 3c59x ethernet card.
Problem:
1). I've compiled kernel v2.0.38 for a minimal system and a system
that has alot of options selected.
2). I'm booting a UMSDOS filesystem off the IDE drive and trying to
mount the SCSI disk and am running into problems.
a).If the SCSI kernel config options "are not" compiled
into the kernel, but Zip100 module support is compiled for the
2.0.38 kernel, the system will boot ok and I can use my 3COM network
card to ping the world. The 3Com network driver is "insmod'" as a
module. See listing (A) below.
b). If SCSI kernel config options "are" compiled
into the kernel, and ZIP100 module support is compiled for the
2.0.38 kernel, the system "will not" boot and will just hang
after recognizing the SCSI adapter card but willl not finish
or display the " XXX instructions downloaded" for Narrow channel B
although Wide Channel A instructions were downloaded. The SCSI disk
WDE 9.1G will not be found and the 3Com network driver isn't loaded.
See listing (B) below.
c). If SCSI kernel config options "are" compiled
into the kernel, and ZIP100 module support is compiled for the
2.0.38 kernel, the system "will" boot and recognize the SCSI disk
IF AND ONLY IF the 3Com network support "isn't" compiled into the
kernel. However, since the 3c59x.o 3Com network module from a
previous compile exists (even with symbol versioning) it will get
loaded into the kernel via modprobe without problem. But, the
only thing I can do with this is to telnet/ftp/ping my local
subnet and can't get to the outside world although IP forwarding
was compiled into the kernel and all the other various protocols to.
See listing (C) below.
CONCLUSION:
1). Both channels share the same interrupt #11 and the 3Com card also
gets interrupt 11. In /proc/interrupts there is "aic7xxx aic7xxx eth0"
on this interrupt with the IDE drive on interrupt 15 and Crystal
sound support with MIDI on interrupt 9.
2). Disabling kernel built in 3Com support when SCSI disk capabilities
are selected will allow the SCSI adapter and disk to be recognized
fully and mounted. With 3Com support, the system will hang during
system boot.
3). These configurations were only done for kernel v2.0.38 when UMSDOS
boots off an IDE drive trying to detect and mount a SCSI vs. UMSDOS
booting off a SCSI and trying to mount an IDE. NOTE: I have
UMSDOS kernel v2.2.1 booting off the SCSI and mounting this IDE
drive without problems. The selection of the Interrupts 11 for
the network and SCSI adaptor are the same as above with the IDE
on interrupt 15. I just haven't tried to put kernel v2.0.38 on
the SCSI to boot and mount the IDE.
4). A problem I had earlier this year when I had kernel 2.0.34 and
was booting the IDE drive and trying to detect the SCSI adapter
and disk, and which exhibited similar boot problems, occurred under the
following condition. When the computer booted and autoexec.bat
loaded the vlm/nvlm novell drivers along with the DOS based
3Com network drivers, followed by the linux v2.0.34 OS by
loadlin v1.6a, it would hang in the same spot. This I suppose
was due to the linux kernel fighting with the MSDOS based
network drivers for the network card interrupts whils't it
was trying to detect the SCSI disk, although the kernel load
sequence hadn't tried to sync and modprobe the 3c59x.o kernel
module yet. Hence the SCSI adaptor interrupts for the kernel where
fighting for the DOS based network driver interrupts. The solution
here was to not load any DOS based 3Com network drivers nor
any vlm/nvlm novell drivers and the system booted ok off the
IDE disk. However, in my current situation, I'm not loading
any DOS or novell drivers.
QUESTION:
Any suggestions? i can send you my config file in for the
cases above.
HERE are the "dmesg" listings..........
