Red Hat Bugzilla – Bug 142979
Xen is broken by patches 1050/1051 AGPGART
Last modified: 2015-01-04 17:14:05 EST
upgrading from kernel 1021 to 1032 broke Xen. System hard locks after
Removing patch #1051 did not resolve the problem but removing #1051
and #1050 did resolve the problem. #1051 does not apply clean without
#1050 and was not tested on its own.
440BX/ZX/DX - 82443BX/ZX/DX host bridge
82371 AG/DB/MB chipset.
No serial port on this machine but the last messages with kernel build
1032 Xen0 as delivered are:
agpgart: Detected an Intel 440BX Chipset.
agpgart: Maximum main memory to use for agp memory: 96M
Kernel build 1021 continues with:
agpgart: unable to get memory for graphics translation table
agpgart: agp_backend_initialize() failed.
agpgart-intel: probe of 0000:00:00.0 failed with error -12
The boot completes and the system is usable on console.
Removing patches #1050 and #1051 from 1032 returns xen0 to a usable
state as observed with build 1021.
patch 1050 mentioned is patch 1951
patch 1051 mentioned is patch 1951
I hit return instead of delete.
