Red Hat Bugzilla – Bug 59164
AS1200/AS4100 crash during kernel boot
Last modified: 2007-04-18 12:39:39 EDT
Description of Problem:
The BOOT kernel crashes during startup on AS1200 and AS4100, making
Version-Release number of selected component (if applicable): alpha-7.2-beta1
Steps to Reproduce:
During boot of the BOOT kernel off the CD, the 2.4.9-14a kernel incorrectly
probes and sets up the PCI bus devices' resources, leaving some devices
incorrectly initialized. Most often this shows up as an infinite loop of
SCSI error messages, since it is often the case that the SCSI controller
is one of the devices incorrectly initialized.
Correct operation, of course... :-)
This is not just a 2.4.9-14a kernel problem; it exists in 2.4.17 as well.
The bug may be exacerbated by the types of devices present; the test machine
on which I had the severe problems had a KZPCM (dual SCSI plus NIC combo
board) on each of the 2 peer PCI buses.
I have a patch that fixes the problems, which I will attach later. (JAE)
Created attachment 44216 [details]
patch for arch/alpha/kernel/core_mcpcia.c to fix AS4100/AS1200 crashes
These systems are outside the scope of the contract and will be marked CLOSED -
The patch is supplied, it is important that this server, which worked with 7.1
release, continue to work. We are not asking for you to do any extra testing,
simply include the fix, so the AS1200 and AS4100 systems can install 7.2
Fixed and working. (ok works on Elliots 4100)...
