| |
Hello List,
This is an IBM xSeries dual-P3 1.0Ghz server box with an IBM ServeRAID 4Mx controller and 3 * IBM 18 Gb SCSI hotswap disks. Base O/S is Trustix 2.2, manually updated with a 2.6.13 kernel built from source and a mkinitrd-4.1.18-2 RPM stolen from FC3 because TSL 2.2's mkinitrd can't handle .ko modules.
After upgrading to kernel 2.6.13, the machine stops at boot during initrd processing. After much head-scratching I've figured out that the "mkdevices /dev" command in the "init" script of the initrd was looping. Hand-editing the init script like this:
echo "Loading ips.ko module" insmod /lib/ips.ko sleep 10 <-------- this line added echo Creating block devices mkdevices /dev
and rebuilding the initrd makes the problem go away. So it's really a timing issue. Everything is fine too if I build the kernel with ips and scsi modules statically linked.
When failing, console output goes like (approx., typed by hand):
Loading scsi_mod.ko module SCSI subsystem initialized Loading sd_mod.ko module Loading ips.ko module input: AT Translated Set 2 keyboard on isa0060/serio0 scsi0 : IBM PCI ServeRAID 7.12.02 Build 761 <ServeRAID 4Mx> Vendor: IBM Model: SERVERAID Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 02 SCSI device sda: 71094272 512-byte hdwr sectors (36400 MB) sda: got wrong page sda: assuming drive cache: write through SCSI device sda: 71094272 512-byte hdwr sectors (36400 MB) sda: got wrong page sda: assuming drive cache: write through sda: sda1 sda2 sda3 sda4 < sda5 sda6 sda7 sda8 > Attached scsi disk sda at scsi0, channel 0, id 0, lun 0 Vendor: IBM Model: SERVERAID Rev: 1.00 Type: Processor ANSI SCSI revision: 02 Vendor: IBM Model: CaVv3 S2 Rev: 0 Type: Processor ANSI SCSI revision: 02 Creating block devices input: ImExPS/2 Generic Explorer Mouse on isa0060/serio1
(stops here... nothing happens anymore, system is *not* hung though, typed characters echo, Ctrl-Alt-Del reboots)
Can anyone provide a hint here? I'm really stuck. Of course I have two possible work-arounds, but I'd really like to understand.
Greets, _Alain_
