My system is a dual processor pentium 133 Tyan motherboard with a AHA2742A-T (Twin Channel) card. I've even seen the boot on a AHA3940 system die (used the 5.0.19 driver on this system). The AHA3940 boot problem only seem to occur on random boots. The 5.0.19 through 5.1.2 aic7xxx code will not work with my AHA2742A-T card. I have a temporary workaround in that I built a 2.0.34 kernel with the 4.1 aic7xxx code and that works. Thanks.

My system is an older EISA/PCI (neptune chipset) TYAN board. The Adaptec SCSI adapter is a AHA2742T (Rev E chip Twin Channel) card. When I booted the 2.0.34 Debian Linux boot disk which has the 5.0.19 aic7xxx driver linked into it the driver paniced the kernel. I then obtained a 2.0.35 source tree and updated the driver to 5.1.2 and the following panic occurs: (scsi0) <Adaptec AHA-274X SCSI host adapter> found at EISA slot 1 (scsi0) Twin Channel, A SCSI ID 7, B SCSI ID 7, 4/255 SCBs (scsi0) Downloading sequencer code... 423 instructions downloaded (scsi0) BRKADRINT error(0xa) Illegal Sequencer Address referenced Sequencer Ram Parity Error (scsi0) SEQADDR=0x1a8 Kernel panic: aic7xxx: unrecoverable BRKADRINT. Based on this message it suggests my board's sequencer ram is bad, but the 4.1 aic7xxx code does not have a problem on this very same system. When I downgraded the 5.0.19 / 2.0.34 kernel to a 4.1 set of aic7xxx code the system boots and runs fine. Any ideas? I have channel A as the secondary channel on this card so channel B is the primary/boot channel.
