Hi. I'm returning to Vector and linux after a long break and I'm a little rusty.
I've installed VL5.8 on a Toshiba Tecra A8 laptop. The main problem is being unable to adjust screen brightness and I compiled a new kernel (2.6.21) to try to get toshset working (unsuccessfully, that's another story).
Booting my new kernel ends in a kernel panic
VFS: Cannot open root device "807" or unknown block (8,07)
Please append a correct "root= " boot option
I can still boot the original kernel from lilo OK which makes it sound like there is a problem with the config of my new kernel, but I don't think it is. I have double checked the sata drivers are included, all the required filesystems. In fact i have also compiled a 2.6.21 from the config of the kernel that works, and the result is the same. Instead I think it is something to do with the boot process
When I go back through dmesg of the working 126.96.36.199 kernel, there is a line that comes up saying
BOOT_IMAGE=188.8.131.52 ro root=807
This does not come from /etc/lilo.conf. I did a grep -r BOOT_IMAGE /boot and the only match was the binary file /boot/map
My systen is a dual boot with WinXP. I have a boot.ini optoin to load lilo and it goes from there. My root partition is /dev/sda7
Is there anything else I should be checking in the kernel config?
What else can I check for clues?
