RE: Adaptec 1540CF (aha1542) not detected
Well, think I may have a handle (vaguely) on the problem (though no solution
yet):
However, the installer cannot detect my SCSI CDROM. I try to choose it
manually, but no such device seems to be listed in /dev (looking for
/dev/sr0 or some such)
I have tried the boot option:
aha1542=0x<base_address>
After looking in depth at
/proc/modules
/proc/interrupts
/proc/iomem
/proc/ioports
it became obvious that the aha1542.ko module was not being loaded by the
installer. (and I suspect that even though the aha1542=xxx boot option is
listed, it may not have been compiled into the kernel either)
So at the beginning of the install process, I alt-F2 to a terminal and
# modprobe aha1542
to load the module
and behold, the adapter is detected!
I now have
/dev/sr0 as my scsi cdrom
** BUT **
big problem:
When I try to mount the cdrom, I get:
Kernel panic: Buffer at physical address > 16Mb used for aha1542
After some online research, it appears that this is a result of a recurring
bug throughout kernels since 2.3.x
(fixed in 2.3.26, recurs around 2.6.3, etc.)
not sure of current patch status, etc. but I'm looking now.
Will post what I find.
