Hi all. I have FC4 installed on: SuperMicro motherboard (Intel E7530 chipset) 2 x Xeon 2,8 4 Gb RAM 14 x Seagate 320Gb in a raid RAID Controller Adaptec SATA AAR-21610SA Periodically the computer hangs up. I don't have errors that are on the monitor when it hangs (there is something about Bug: spinlock on cpu#0 java/2 0192 f765e834 (not tainted)) but when restarting after a hang it gives: <c04056e3> do_invalid_op+0x0/0x9d <c0405774> do_invalid_op+0x91/0x9d <f8872ffa> aac_intr_normal+0x1aa/0x246 [aacraid] <c04242ca> vprintk+0x2a5/0x2c <c041cbb7> __wake_up+0x29/0x3c <c052165e> add_timer_randomness+0xfd/0x104 <c04048cb> error_code+0x4f/0x54 <f8872ffa> aac_intr_normal+0x1aa/0x246 [aacraid] <f88730f5> aac_rx_intr+0x30/0xfd [aacraid] <c04478e8> handle_IRQ_event+0x21/0x4a <c044799d> __do_IRQ+0x8c/0xdf <c0406103> do_IRQ+0x62/0x7d ======================= <c0404772> common_interrupt+0x1a/0x20 BUG: warning at kernel/panic.c:138/panic() (Not tainted) <c042368d> panic+0x16a/0x189 <c040540f> die+0x24c/0x263 <c04056e3> do_invalid_op+0x0/0x9d <c0405774> do_invalid_op+0x91/0x9d <f8872ffa> aac_intr_normal+0x1aa/0x246 [aacraid] <c04242ca> vprintk+0x2a5/0x2c <c041cbb7> __wake_up+0x29/0x3c <c052165e> add_timer_randomness+0xfd/0x104 <c04048cb> error_code+0x4f/0x54 <f8872ffa> aac_intr_normal+0x1aa/0x246 [aacraid] <f88730f5> aac_rx_intr+0x30/0xfd [aacraid] <c04478e8> handle_IRQ_event+0x21/0x4a <c044799d> __do_IRQ+0x8c/0xdf <c0406103> do_IRQ+0x62/0x7d ======================= <c0404772> common_interrupt+0x1a/0x20 When restarting again, everything is normal until next hang.
