I tried to use ccd(Concatenated Disk Driver) on 2.2-BETA. I recompired a kernel for ccd and rebooted. And I executed ccdconfig. But kernel was in a panic. Messages: vm_bounce_alloc: b_bufsize(0x0) < b_bcount(0x200) !! panic: vm_bounce_alloc When I comment out "options BOUNCE_BUFFER" and recompile kernel, ccd works fine (but memory size is only 16MB). help me... My kernel configure file: ---------------------------- machine "i386" cpu "I486_CPU" ident SFX maxusers 8 options INET options FFS options NFS options PROCFS options "COMPAT_43" options SCSI_DELAY=5 options BOUNCE_BUFFERS options FAILSAFE options USERCONFIG options MAXCONS=2 config kernel root on wd0 controller isa0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr disk wd0 at wdc0 drive 0 controller aha0 at isa? port "IO_AHA0" bio irq ? drq 5 vector ahaintr controller scbus0 device sd0 device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr device npx0 at isa? port "IO_NPX" irq 13 vector npxintr device ed0 at isa? port 0x280 net irq 9 iomem 0xd8000 vector edintr pseudo-device loop pseudo-device ether pseudo-device log pseudo-device pty 4 pseudo-device ccd 1 ---------------------------- Koichi MOURI
