Hi All, Im wondering whether any one has got a solution to this problem I have found plenty of info about it in google groups etc.. but cant seem to find a solid fix We are running FreeBSD 4.3 with the following hardware: Gigabyte GA-6EXDR MB (with on board LSI SCSI card disabled in the bios for FreeBSD incompatability problems) Adaptec 29160 SCSI card 3 X Seagate 73 GIG SCSI ST373405LC HDD All in a 1ru chasis and get these errors dev = #da/0x20004, block = 43584, fs = /disk/00 panic: ffs_blkfree: freeing free block mp_lock = 00000001; cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 syncing disks... 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 giving up on 3 buffers Uptime: 25d5h24m50s We updated to the latest mother board bios , and the problem is still as often , but now its a new error This is under exactly the same circumsances /kernel: panic: ffs_clusteralloc: map mismatch /kernel: mp_lock = 00000001; cpuid = 0; lapic.id = 00000000 /kernel: boot() called on cpu#0 /kernel: /kernel: syncing disks... 155 155 74 39 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 /kernel: giving up on 25 buffers /kernel: Uptime: 2h30m20s /kernel: Automatic reboot in 15 seconds - press a key on the console to abort This is fairly random (it could be up for 2 hours or 2 days) It just doesnt happen on one machine it happens on up to 10 seperate we have (all the same hardware) But happens always with high SCSI I/O and writing big files We can simulate it fairly easily testing with Bonnie writing 1-2 gig files I have tried FreeBSD 4.4 with no difference plus different revisions of adaptec 29160 card Also with soft updates on or off Any ideas Please email me if you want further info Thanks Tim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
