The soft lockup basically means it was hung in asd_read_ocm(): aic94xx: Adaptec aic94xx SAS/SATA driver version 1.0.2 loaded GSI 49 (level, low) -> CPU 0 (0x0000) vector 62 ACPI: PCI Interrupt 0000:c0:01.0[A] -> GSI 49 (level, low) -> IRQ 62 aic94xx: found Adaptec AIC-9410W SAS/SATA Host Adapter, device 0000:c0:01.0 OCM is not initialized by BIOS,reinitialize it and ignore it, current IntrptStatusis 0x0 BUG: soft lockup detected on CPU#0!
