Hello, We are getting the following errors at random times during mount. Sometimes the machine boots fine into multi-user mode and then typing umount /u1 mount /u1 generates this error EXT2-fs error (device 08:11): ext_check_blocks_bitmap: Block #191 of the inode table in group 165 is marked free EXT2-fs error (device 08:11): ext_check_blocks_bitmap: Wrong free blocks count for group 165, sotred = 7898, counted = 7899 EXT2-fs error (device 08:11): ext2_check_blocks_bitmap: Wrong free blocks count in super block, sotred = 8603602, counted = 8603603 Some times on reboot the machine boots into single user mode and fsck is required to fix the same type of errors We have tried the following kernels and still produce the same results, 2.0.35, 2.0.36, 2.2.1 The drives in question are IBM DDRS-39130 (9130MB) The adapter an Adaptec AIC-7895 We are using the Linux Adaptec AIC7xxx scsi driver We are also running RedHat v5.2 Has anybody encountered this before? What type of problem does this imply? This happens on all 5 brand new IBM drives.

We would have to get one of these particular drives into the test lab for us to accurately track down any problems. I will add this to our list of needed hardware.
I was wondering if you might have a timetable for a solution to this particular problem. We are using a Tyan 1836DLU motherboard with IBM DDRS- 39130W 9.1GB drives. We're really stumped over here. We have tried it with an Adaptec 2940UW adapter card and we still get the problem. However, when we put the adapter card into a Dell Optiplex GXM5166, the drive has no problem. We also have a 4GB drive (IBM 34560W) with the root partition on it and do not seem to see a problem. Note, that the subject drive model is WRONG, it is the IBM DDRS-39130 Thanks for you help, Ido
I seem to have the same problem here, on an Asus T2P4 w/ Adaptec 2940U2W-LVD and two IBM DNES-318350/LVD. I can partition the drive, and make a file system (ext2) with the default mke2fs settings on it, and fsck reports everything is fine. But when I create a partition >8GB (the drive is 17.5GB) and mount it, the drive gets damaged with errors similar to those above, and fsck reports even more errors. One partitions up to 8GB work, but when I split the drive into two partitions of the same size and restart fdisk, it reports that the second one does not end on cylinder boundary (it ends on the last cylinder though). I have tried the bootparams "linear" and "aic7xxx=extended", but that does not help either. As the aic7xxx module also lists these drives wrong at boottime ("IBM DNES-3" followed by garbage) and the controller itself doesn't, might there be a problem with this module? Thanks for your help.
Oops, I forgot to mention it: I use RedHat 6.0.
I suspect that these problems have been fixed by later kernel's. Please reopen this bug if not.
