I was just attempting to configure some old SCSI drivers into a serially concatenated ccd, and I'm getting a panic in vm_bounce_alloc(): panic: vm_bounce_alloc: Unmapped page The trace from the crash dump is: #0 0xf010f3e3 in boot () #1 0xf010f6b2 in panic () #2 0xf01b7edf in vm_bounce_alloc () #3 0xf018a737 in sd_strategy () #4 0xf0187588 in scsi_strategy () #5 0xf018a244 in sdstrategy () #6 0xf01362be in spec_strategy () #7 0xf0101356 in ccdstart () #8 0xf010129b in ccdstrategy () #9 0xf0194240 in readdisklabel () #10 0xf010220a in ccdgetdisklabel () #11 0xf0101b54 in ccdioctl () #12 0xf0136157 in spec_ioctl () #13 0xf0132d7c in vn_ioctl () #14 0xf0116fb3 in ioctl () #15 0xf01b36a3 in syscall () #16 0x135b5 in ??

() The ccd.conf file is: ccd0 0 none /dev/sd1s1f /dev/sd2s1e /dev/sd0s1f and the partitions are: # /dev/rsd1s1c: # size offset fstype [fsize bsize bps/cpg] c: 8386733 0 unused 0 0 # (Cyl. 0 - 8386732) f: 8386733 0 4.2BSD 0 0 0 # (Cyl. 0 - 8386732) # /dev/rsd2s1c: # size offset fstype [fsize bsize bps/cpg] c: 4197405 0 unused 0 0 # (Cyl. 0 - 4197404) e: 4197405 0 4.2BSD 0 0 0 # (Cyl. 0 - 4197404) # /dev/rsd0s1c: # size offset fstype [fsize bsize bps/cpg] c: 2061108 0 unused 0 0 # (Cyl. 0 - 2061107) e: 409600 0 4.2BSD 0 0 0 # (Cyl. 0 - 409599) f: 1651508 409600 4.2BSD 0 0 0 # (Cyl. 409600 - 2061107) This happens with both 2.2.8-RELEASE, and a recent 2.2.8-STABLE. The box in question is an old 486/DX33, with 40MB DRAM, and an AHA1542C SCSI controller. The BOUNCE_BUFFERS option is set in the kernel config. I've been using the disks for a long time on this box, in a non-ccd config, without any problems. Anyone have any suggestions?
