Hello list, I am following the "Xenomai quick build guide" http://www.xenomai.org/index.php/Xenomai_quick_build_quide to install xenomai version 2.4.4 with linux kernel 2.6.25.11. I am running ubuntu on an IBM Thinkpad Z60t. When I try to boot the 2.6.25.11-xenomai-2.4.4 image I get the following kernel panic error:
> Please append a correct "root=" boot options; here are teh available > partitions: > 0100 65536 ram0 (driver?) > 0101 65536 ram1 (driver?) ... > 0300 78150744 hda driver: ide-disk > 0301 76670181 hda1 > 0302 1 hda2 > 0305 1477948 hda5 > > Kernel panic - not syncing: VFS: Unable to mount root fs on unkown-block (0,0) My xenomai entry in /boot/grub/menu.lst is: > title kernel 2.6.25.11 with xenomai 2.4.4 and Ubuntu 8.04 > root (hd0,0) > kernel /boot/vmlinuz-2.6.25.11-xenomai-2.4.4 root=/dev/sda1 ro > xeno_nucleus.xenomai_gid=1001 I googled this problem, and the main suggestion that I found is to compile my hard disk drivers not as a module, but compile it into the kernel itself. I am not sure if I am doing this correctly. In an attempt to do this, I selected the following options in menuconfig: > Device Drivers ---> SCSI device support ---> <*> SCSI disk support (because my disk is SCSI) > Device Drivers ---> ATA/ATAPI/MFM/RLL support ---> Include IDE/ATA-2 DISK > support > In the section *** PCI IDE chipsets support *** of Device Drivers ---> I > compiled into the kernel all the drivers that were marked as modules. > In the section File systems ---> I compiled into the kernel > <*> Ext3 journalling file system support > [*] Ext3 extended attributes > [*] Ext3 POSIX Access Control Lists > [*] Ext3 Security Labels Am I missing an important options?

But a posteriori, through experience, he finds to his astonishment that he is not free, but subjected to necessity, that in spite of all his resolutions and reflections he does not change his conduct, and that from the beginning of his life to the end of it, he must carry out the very character which he himself condemns."
