Boot log of 2.6.12-1.1450_FC4

boot log of kernel 2.6.13-1.1558_FC5
booting with "acpi=force pci=noacpi" works around the problem. This laptop is rather old, so APM is used instead of ACPI by default. And pci=noacpi is also needed in this case to properly handle IRQs. Should no longer be a problem because the ACPI cutoff date is enabled again Can you close the bug if current rawhide is ok ? yes, DMA works again on rawhide, both with ACPI and with APM. thanks. |
Something changed between 2.6.12-1.1450_FC4 and 2.6.13-1.1558_FC5 in the IDE code. The disk of my old 770Z thinkpad no longer starts with dma enabled. It fails with dma_timer_expiry: dma status == 0x21, DMA timeout error. The workaround to boot with ide=nodma works for me. boot logs follow as attachment.
