Hi, Yesterday I upgrade my box to newest latest stable kernel and after a time I got an error from my raid 10 array: After reboot the array was OK and the system is running OK but how long? Please give me an addvice what to do ;-) Best Regards Juraj Hantak Kernel: latest stable: 2.6.13-2 dmesg: Sep 22 12:22:25 mailhub kernel: Red Hat/Adaptec aacraid driver (1.1.2-lk2 Sep 20 2005) Sep 22 12:22:25 mailhub kernel: ACPI: PCI Interrupt 0000:03:08.0[A] -> GSI 17 (level, low) -> IRQ 169 Sep 22 12:22:25 mailhub kernel: AAC0: kernel 4.2-0[7348] Sep 22 12:22:25 mailhub kernel: AAC0: monitor 4.2-0[7348] Sep 22 12:22:25 mailhub kernel: AAC0: bios 4.2-0[7348] Sep 22 12:22:25 mailhub kernel: AAC0: serial c3c94b Sep 22 12:22:25 mailhub kernel: scsi0 : aacraid Sep 22 12:22:25 mailhub kernel: Vendor: ADAPTEC Model: mailusers Rev: V1.0 Sep 22 12:22:25 mailhub kernel: Type: Direct-Access ANSI SCSI revision: 02 diagnostic dump text Remote Computer: .
