patch for arch/alpha/kernel/pci.c to fix quirk_cypress() bug
Does this happen on a DS20E with exactly 2GB memory? That's what our system has. With a 2.4.9 kernel, this will not happen with exactly 2GB of memory - more than 2GB is required to encounter this bug (DS20 / DS20E support up to 4GB of memory). The patch has been added to the kernel for the upcoming release. I'm closing this bug because it was fixed in the Feb 22 release. |
Description of Problem: On a DS20E with more than 2GB of memory and SCSI controller on PCI bus #0, the install crashes. Version-Release number of selected component (if applicable): alpha-7.2-beta1 How Reproducible: Always, but not exactly the same symptoms. Steps to Reproduce: 1. DS20 or DS20E with more than 2GB of memory 2. SCSI controller (doesn't matter what kind) on PCI bus #0 3. full ("Everything") install Actual Results: During the install, the kernel will crash with various symptoms, sometimes a panic, sometimes just a complete hung machine. Expected Results: Flawless install, of course... :-) Additional Information: The bug is caused by a flawed workaround for a CYPRESS chipset limitation. The workaround attempts to adjust a resource if it finds more than 2GB of memory, and incorrectly calculates the adjustment. I will attach a bugfix for this problem. (JAE)
