I've got a few compilation errors on head. Before I try it, is it possible to backport the 76d78300a6eb8b7f08e47703b7e68a659ffc2053 change to 2.6.24.y?
Please just try this patch instead, it's what I am planning to submit to -stable and add to Gentoo if you report success.

From: Nick Cheng <[EMAIL PROTECTED]> Partial backport of 76d78300 ("arcmsr: updates (1.20.00.15)") by Daniel Drake <[EMAIL PROTECTED]>. Removes pci_alloc_consistent usage, which should not be used when IRQs are disabled for portability reasons. Fixes a spew of dma_alloc_coherent irqs_disabled() warnings. diff --git a/drivers/scsi/arcmsr/arcmsr_hba.c b/drivers/scsi/arcmsr/arcmsr_hba.c index f4a202e..4f9ff32 100644 --- a/drivers/scsi/arcmsr/arcmsr_hba.c +++ b/drivers/scsi/arcmsr/arcmsr_hba.c @@ -1380,12 +1388,13 @@ static int arcmsr_iop_message_xfer(struct AdapterControlBlock *acb, \ case ARCMSR_MESSAGE_READ_RQBUFFER: { unsigned long *ver_addr; - dma_addr_t buf_handle; uint8_t *pQbuffer, *ptmpQbuffer; int32_t allxfer_len = 0; + void *tmp; - ver_addr = pci_alloc_consistent(acb->pdev, 1032, &buf_handle); - if (!ver_addr) { + tmp = kmalloc(1032, GFP_KERNEL|GFP_DMA); + ver_addr = (unsigned long *)tmp; + if (!tmp) { retvalue = ARCMSR_MESSAGE_FAIL; goto message_out; } @@ -1421,18 +1430,19 @@ static int arcmsr_iop_message_xfer(struct AdapterControlBlock *acb, \ memcpy(pcmdmessagefld->messagedatabuffer, (uint8_t *)ver_addr, allxfer_len); pcmdmessagefld->cmdmessage.Length = allxfer_len; pcmdmessagefld->cmdmessage.ReturnCode = ARCMSR_MESSAGE_RETURNCODE_OK; - pci_free_consistent(acb->pdev, 1032, ver_addr, buf_handle); + kfree(tmp); } break; case ARCMSR_MESSAGE_WRITE_WQBUFFER: { unsigned long *ver_addr; - dma_addr_t buf_handle; int32_t my_empty_len, user_len, wqbuf_firstindex, wqbuf_lastindex; uint8_t *pQbuffer, *ptmpuserbuffer; + void *tmp; - ver_addr = pci_alloc_consistent(acb->pdev, 1032, &buf_handle); - if (!ver_addr) { + tmp = kmalloc(1032, GFP_KERNEL|GFP_DMA); + ver_addr = (unsigned long *)tmp; + if (!tmp) { retvalue = ARCMSR_MESSAGE_FAIL; goto message_out; } @@ -1482,7 +1492,7 @@ static int arcmsr_iop_message_xfer(struct AdapterControlBlock *acb, \ retvalue = ARCMSR_MESSAGE_FAIL; } } - pci_free_consistent(acb->pdev, 1032, ver_addr, buf_handle); + kfree(tmp); } break;
