Additional Notes + + 4.1. Known/Unresolved or FYI Issues + + * Under SuSE Linux Enterprise 7, the driver may fail to operate + correctly due to a problem with PCI interrupt routing in the + Linux kernel. Please contact SuSE for an updated Linux + kernel. + + 4.2. Third-Party Compatibility Issues + + * Adaptec only supports Ultra320 hard drives running + the latest firmware available. Please check with + your hard drive manufacturer to ensure you have the + latest version. + + 4.3. Operating System or Technology Limitations + + * PCI Hot Plug is untested and may cause the operating system + to stop responding. + * Luns that are not numbered contiguously starting with 0 might not + be automatically probed during system startup. This is a limitation + of the OS. Please contact your Linux vendor for instructions on + manually probing non-contiguous luns. + * Using the Driver Update Disk version of this package during OS + installation under RedHat might result in two versions of this + driver being installed into the system module directory. This + might cause problems with the /sbin/mkinitrd program and/or + other RPM packages that try to install system modules. The best + way to correct this once the system is running is to install + the latest RPM package version of this driver, available from + http://www.adaptec.com. + + +5.
