After upgrading kernel from 2.6.9-rc2 to 2.6.9, deconfiguring network interfaces started to cause oops. Machine: Athlon XP 2500+, 1Gb RAM (no highmem), all hardware is linux-friendly, working fine for more than year. Kernel: stock vanilla 2.6.9 kernel, no special patches, except PAGE_OFFSET moved to 0x80000000. Distro: Debian unstable/sid i386 (with the most recent updates). GCC: Debian 3.3.5-1 from Debian package. Oops: 100% reproducible. I will be glad to provide any additional information. Please Cc: me beacuse I'm not subscribed to mailing list. Here is screenshot (copied by hand because system was unusable): Deconfiguring network interfaces...
