I tried 2.4.5-ac16 on my Asus A7A266 w/ Athlon because the fixnotes sounded like it might address the simplex vs. DMA problem that I reported a while back, but I get a kernel panic early in the boot sequence every time I try to boot. FYI, 2.4.5-ac14 boots and runs OK, except for the disabled DMA and frequent SMBus resets when I try to run lm_sensors. (The only difference in the .config between -ac14 and -ac16 is that for -ac16 I enabled the new ALI chipset fix.) Possibly relevant, notice that 2.4.5-ac14 reports the chipset as "ALI15X3" during the boot sequence, whereas the board's documentation says that it's actually an ALi M1535D+. It also gives this message at boot time, which I will send to the indicated address in a separate message: Jun 19 15:49:36 pollux kernel: PCI: Found IRQ 9 for device 00:0d.0 Jun 19 15:49:36 pollux kernel: Redundant entry in serial pci_table.
