Yes (conference is now over). I backed out the sysctl_check patch from 2.6.24-rc3 and, indeed, got a working kernel. The working kernel (was probably 2.6.24-rc3 less sysctl_check patch, but might have been a 2.6.23 variant) has the following in /sys/block alpha:~# ls -l /sys/block/ total 0 drwxr-xr-x 5 root root 0 2007-12-08 08:55 fd0 drwxr-xr-x 6 root root 0 2007-12-08 08:55 hde drwxr-xr-x 5 root root 0 2007-12-08 08:55 hdf drwxr-xr-x 10 root root 0 2007-12-08 08:55 sda drwxr-xr-x 9 root root 0 2007-12-08 08:55 sdb alpha:~# ls -l /sys/block/sda total 0 -r--r--r-- 1 root root 8192 2007-12-08 08:55 capability -r--r--r-- 1 root root 8192 2007-12-08 08:55 dev lrwxrwxrwx 1 root root 0 2007-12-08 08:55 device -> ../../devices/pci0001:01/0001:01:06.0/host0/target0:0:1/0:0:1:0 drwxr-xr-x 2 root root 0 2007-12-08 08:55 holders drwxr-xr-x 3 root root 0 2007-12-08 08:55 queue -r--r--r-- 1 root root 8192 2007-12-08 08:55 range -r--r--r-- 1 root root 8192 2007-12-08 08:55 removable drwxr-xr-x 3 root root 0 2007-12-08 08:55 sda1 drwxr-xr-x 3 root root 0 2007-12-08 08:55 sda2 drwxr-xr-x 3 root root 0 2007-12-08 08:55 sda3 drwxr-xr-x 3 root root 0 2007-12-08 08:55 sda4 drwxr-xr-x 3 root root 0 2007-12-08 08:55 sda5 -r--r--r-- 1 root root 8192 2007-12-08 08:55 size drwxr-xr-x 2 root root 0 2007-12-08 08:55 slaves -r--r--r-- 1 root root 8192 2007-12-08 08:55 stat lrwxrwxrwx 1 root root 0 2007-12-08 08:55 subsystem -> ../../block --w------- 1 root root 8192 2007-12-08 08:55 uevent alpha:~# grep . /sys/block/sda/*/dev /sys/block/sda/sda1/dev:8:1 /sys/block/sda/sda2/dev:8:2 /sys/block/sda/sda3/dev:8:3 /sys/block/sda/sda4/dev:8:4 /sys/block/sda/sda5/dev:8:5 The broken kernel (2.6.24-rc3) has the following in /sys/block alpha:~# ls -l /sys/block/ total 0 drwxr-xr-x 5 root root 0 Dec 8 09:22 fd0 drwxr-xr-x 6 root root 0 Dec 8 09:22 hde drwxr-xr-x 5 root root 0 Dec 8 09:23 hdf drwxr-xr-x 10 root root 0 Dec 8 09:22 sda drwxr-xr-x 9 root root 0 Dec 8 09:23 sdb alpha:~# ls -l /sys/block/sda total 0 -r--r--r-- 1 root root 8192 Dec 8 09:22 capability -r--r--r-- 1 root root 8192 Dec 8 09:22 dev lrwxrwxrwx 1 root root 0 Dec 8 09:23 device -> ../../devices/pci0001:01/0001:01:06.0/host0/target0:0:1/0:0:1:0 drwxr-xr-x 2 root root 0 Dec 8 09:22 holders drwxr-xr-x 3 root root 0 Dec 8 09:22 queue -r--r--r-- 1 root root 8192 Dec 8 09:22 range -r--r--r-- 1 root root 8192 Dec 8 09:22 removable drwxr-xr-x 3 root root 0 Dec 8 09:22 sda1 drwxr-xr-x 3 root root 0 Dec 8 09:22 sda2 drwxr-xr-x 3 root root 0 Dec 8 09:22 sda3 drwxr-xr-x 3 root root 0 Dec 8 09:22 sda4 drwxr-xr-x 3 root root 0 Dec 8 09:22 sda5 -r--r--r-- 1 root root 8192 Dec 8 09:22 size drwxr-xr-x 2 root root 0 Dec 8 09:22 slaves -r--r--r-- 1 root root 8192 Dec 8 09:22 stat lrwxrwxrwx 1 root root 0 Dec 8 09:22 subsystem -> ../../block --w------- 1 root root 8192 Dec 8 09:22 uevent alpha:~# grep . /sys/block/sda/*/dev /sys/block/sda/sda1/dev:8:1 /sys/block/sda/sda2/dev:8:2 /sys/block/sda/sda3/dev:8:3 /sys/block/sda/sda4/dev:8:4 /sys/block/sda/sda5/dev:8:5 I failed to spot any difference (other than the formatting of the dates) between the two!
