Cacah Partisi SCSI Maks Pada Linux
Sempat panik ketika salah satu partisi (yang berukuran paling besar) pada disk eksternal saya tidak dapat di-mount, bahkan tidak dikenal oleh Linux. Cari-cari info kesana kemari, ternyata ini limitasi device SCSI, yang hanya menyediakan 16 nomor minor untuk setiap major. Dari file Documentation/devices.txt di source kernel:
Jadi misalnya hard disk tersebut dikenal sebagai /dev/sdb, maka hanya akan ada /dev/sdb1 s/d /dev/sdb15 yang dapat diakses oleh Linux. Karena disk eksternal saya memakai interface USB, yang oleh Linux ditangani melalui subsistem SCSI, maka pembatasan tersebut berlaku. Kelihatannya tidak mudah membongkar pembatasan tersebut (belum sempat dicoba sih), karena berakibat panjang pada pergeseran nomor minor block device SCSI. Bila minor untuk /dev/sda kita perbesar dari 16 ke 32, maka nomor awal minor sdb bergeser dari 16 ke 32, sdc dari 32 ke 48, dst. Cacah device SCSI yang didukung akan berkurang dari 16 ke 8. Barangkali untuk mayoritas pengguna, 8 device SCSI yang masing-masing bisa memiliki 32 sub-device, lebih bermanfaat daripada 16 device yang masing-masing hanya memiliki 16 sub-device.8 block SCSI disk devices (0-15)
0 = /dev/sda First SCSI disk whole disk
16 = /dev/sdb Second SCSI disk whole disk
32 = /dev/sdc Third SCSI disk whole disk
...
240 = /dev/sdp Sixteenth SCSI disk whole disk
Partitions are handled in the same way as for IDE
disks (see major number 3) except that the limit on
partitions is 15.

Patch for Broadcom NetXtreme II 10GbE on kernel 2.6.22
While preparing some IBM x3950 M2 machines, I got several problems. Distro used is Debian Lenny AMD64 varian, which provides kernel 2.6.22 and 2.6.26. Machine couldn't boot kernel 2.6.26, but this problem needs proper IPMI setup or local access (which I don't have now). So back to kernel 2.6.22. Next problem is that 2.6.22 doesn't support Broadcom BCM57710 10GbE. Searching IBM's support, I find potential driver v1.45.20, but they are for SLES/RHEL. Time to get dirty!
First try, too many errors:
After long warming up, last effort involving GNU global (gtags, htags), creating cross references for kernel 2.6.21, 2.6.22, and 2.6.28, path to solution started to appear. The culprit is file bnx2x-compat.h which is a compatibility header created to make this driver compatible to multiple kernel versions. Line #4 originally:$ make KVER=2.6.22-bnx
make -C /lib/modules/2.6.22-bnx/build M=`pwd` modules
