Hi,

the current 2.4.1 can not found the mesh scsi controller on my 7500/100.
It doesnt work with bootx and boot fd:vmlinux.coff.

Any ideas how to fix it?

Hmm, I will try without the loop device, but I guess that will not help.
If I use a ramdisk I get the attached output.

    I don't know if that's related, but I have a 7300 and
also had some problem with the internal SCSI.

    The internal bus can do 10 Mo/s, so in 2.2 kernels I
always used this value instead of the default 5 Mo/s. Now
when I tried to use 2.4, I could not boot with the same
modification. The SCSI is well recognized (I don't have the
dmesg here), but when trying to read the disk it stopped by
saying something like /dev/sdb: READ capacity failed.

    I never had this with 2.2, and 2.4 with the default max
speed of 5 Mo/s works fine. Note that I mostly use another
disk on an UW Formac card, so it's not important to me.
