Problems with kernel 2.6.1 on alpha (scsi, modules, unaligned trap)

[Thomas Steudten]

Hello

After some trouble to port my linux kernel on alpha sx614 from kernel
2.4.21 to 2.6.1 i collect here my problems found. Sure, on some alpha
systems this problems aren´t there.

Kernel 2.6.1:
1. BUG: "unaligned trap" in kernel mode (patch there, but not in the 2.6.1 
mainline)
2. BUG: "Relocation overflow vs section" by trying to load some modules 
with modprobe or insmod (patch there, but not in the 2.6.1 mainline)
3. Kernel boot message "***WARNING*** No MII transceivers found" after
soft reboot (no power off/on).
4. Kernel boot message "Unable to reserve mem region #2:1000@a051000 for 
device 0000:00:07.0" "aic7xxx: I/O ports already in use, ignoring."
5. Some modules (floppy, lp, loop..) won´t be autoloaded any more since 
2.4.21. There´s no block-major aso. request in the kernel-ring buffer.
I have /etc/modules.conf and /etc/modprobe.conf with modutils-2.4.21-23.1
and depmod -V: module-init-tools 3.0-pre5. How i can track this down?

Else no major problems with this kernel until know.
(I think the ipt_unclean from netfilter and the kerneld (or whatever) are
gone in 2.6.x) Sorry, if i miss something to read.
