kernel panic while booting

I get a kernel panic while booting my SuSE 8.1 with kernel 2.4.19. After having compiled the kernel I get the following messages when booting without distinction the older kernel and the new one too. Instead I can boot the box using the CD and choosing manual install, then loading ips.o and aic7xxx.o modules and finally choosing start installed OS. I use hardware RAID and LVM with reiser on a NetFinity. These are the messages: VFS: Mounted root (ext2 filesystem) Loading module ips Using /lib/modules/2.4.19-4GB/kernel/drivers/SCSI/ips.o (ips0) unable to read config from controller /lib/modules/2.4.19-4GB/kernel/drivers/SCSI/ips.o: init module: no such device Loading module aic7xxx Using /lib/modules/2.4.19-4GB/kernel/drivers/scsi/aic7xxx/aic7xxx.o scsi1: Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.8 aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCB Loading module reiserfs.o Using /lib/modules/2.4.19-4GB/kernel/fs/reiserfs/reiserfs.o kmod: failed to exec /sbin/modprobe -s -k block-major-8, errno=2 VFS: Cannot open root device "sdg1" or 08:61 Please append a correct "root=" boot option Kernel Panic: VFS: Unable to mount root fs on 08:61 Thank you in advance for every help.
