Hi Jan, Which firmware version is that? I get similar errors under a high load (rebuilding sw raid1 partitions) with sequencer Firmware version 1.1 (V28), which will eventually hang my box. Prev fw versions would also hang in similar situations. My box being OpenSuSE 10.3, a 2.6.22.13-0.3-default kernel, 2x quad core Xeon CPU E5345 @ 2.33GHz stepping 0b, 14G of DDR2-667 memory, and a Adaptec 48300 (AIC-9410W SAS/SATA Host Adapter, device 0000:05:02.0) directly connected to two SEAGATE ST3146855SS My 2 bits. --Keith Hopkins
