Hi,
I've got a little problem.
I have a Adaptec AIC-7770 adapter and hard disk. I made a partitons on it
under 2.0.35, and leter a I've upgraded to 2.0.36. Both of them (2.0.35
and 2.0.36 has the same SCSI configuration).
Under 2.0.36 fdisk display errors:
------------------------------------------------------
Using /dev/sda as default device!
Command (m for help):
Disk /dev/sda: 255 heads, 63 sectors, 274 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Begin Start End Blocks Id System
/dev/sda1 1 1 64 513008 83 Linux native
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 1, 1) logical=(0, 0, 33)
Partition 1 has different physical/logical endings:
phys=(500, 63, 32) logical=(63, 221, 30)
Partition 1 does not end on cylinder boundary:
phys=(500, 63, 32) should be (500, 254, 63)
/dev/sda2 502 64 80 123904 82 Linux swap
................
--------------------------------------------------------
,but everything is clear under 2.0.35.
It's strange but under 2.0.36 system is working ok, If I hadn't run fdisk
I would have never discover this error.
I attached dmesg files from 2.0.35 and 2.0.36
What should I do?
