| |
I tried to use vanilla 2.6.36-rc8 and failed. While trying track down the random oopses, bugs and lockups the problem appeared to get broader and broader. In fact the best description I can come up with is loading a module with at least one dependency.
Steps to reproduce: 1) Get 2.6.36-rc8. 2) Use my config (attached). 3) Compile it on amd64. (I used gcc 4:4.4.5-1 from Debian Sid.) 4) Get qemu. (I used 0.12.5+dfsg-2 from Debian Sid.) 5) Create an initramfs that contains the modules and some shell. 6) qemu-system-x86_64 -m 256 -kernel vmlinuz-2.6.36-rc8 -initrd foo.cpio.gz 7) load a module. If it does not crash, try more.
This is also reproducible without qemu for me. The most reliable module was sky2 (both inside and outside qemu). Also loading ohci_hcd caused a variety of oopses and bugs on my system. Note that not all modules caused problems. For instance the dependencies for sky2 (bitrev and crc32) could be loaded just fine.
