Folks,
Since approx. a half year I have run two servers with CentOS4, all was running very stable.
Then I upgraded to CentOS5 (fresh install). The servers are running quite unstable since the upgrade. The system is freezing after short uptime.
I suspect the driver for the 3ware controller, because I got such error messages:
3w-xxxx: scsi0: Character ioctl (0x1f) timed out, resetting card. 3w-xxxx: scsi0: Character ioctl (0x1f) timed out, resetting card. 3w-xxxx: scsi0: Character ioctl (0x1f) timed out, resetting card.
(lots of repeats of this messages)

After some time (few hours) the systems are completely freezing, no display of errors on the console or logs
Here some relevant data of my system:

It cannot be a 3ware hardware error, because the controller was exchanged with the same results afterwards.
Any hints are very welcome.
Thanks,
