The above tracing was caused by CONFIG_SYSFS_DEPRECATED=y and by setting
this to n, the tracing disappeared.. Still, all my network cards are
non-functional. Entries in /sys/class/net are bogus:
/ # cd /sys/class/net/
/sys/class/net # ls
eth1 eth44 eth54 lo
/sys/class/net # cd eth1
-bash: cd: eth1: No such file or directory
/sys/class/net # ls -l eth1
lrwxrwxrwx 1 root root 0 Apr 26 07:15 eth1 ->
../../devices/pci0000:00/0000:00:12.0/net/eth0
/sys/class/net # cd ../../devices/pci0000\:00/0000\:00\:12.0/net/eth0
-bash: cd: ../../devices/pci0000:00/0000:00:12.0/net/eth0: No such file
or directory
Do you know of any patches I need to revert/apply? Anyway, I have to
boot back to this kernel and find out more what's going on.
