I'm tring to get a CCD going as an experiment and it's causing the kernel to panic. The hardware is: ASUS P120 motherboard, 128MB RAM, crappy old Adaptec ISA card (aha driver) and 3 x Maxtor 2GB drives. (ISA video, no ether yet) I'm using the adaptec card until I get some decent buslogic PCI cards. (I've had LOTS of problems with Adaptec 2940 PCI cards!) Drive 0 is the root disk and has /, swap, /usr and /var. Drives 1 & 2 are setup identical, 64MB swap partition (b) and the rest empty (partition f) for the ccd. (I'm not using the swap partitions yet, but read that it was a bad thing the have the ccd partitions at the start of the disk) I built a kernel with the ccd driver present as it says in the man page, did a cd /dev ; sh MAKEDEV ccd0 with no problems. Then I did: ccdconfig -c -v ccd0 32 none /dev/sd1f /dev/sd2f which resulted in a kernel panic. The message is: vm_bounce_alloc: b_bufsize(0x80) < b_count(0x200) !! panic: vm_bounce_alloc followed by the usual syncing disks bit. The number in the b_bufsize() varies from crash to crash. Am I doing anything obviously wrong? Gordon
