Xen is broken by patches 1050/1051 AGPGART
Last modified: 2015-01-04 17:14:05 EST
Patch1950: linux-2.6.9-agp-missing-cacheflushes.patch Patch1951: linux-2.6.9-agp-posting-bugs.patch upgrading from kernel 1021 to 1032 broke Xen. System hard locks after agpgart message. 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. NM2360 video. 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 _ *hard lock* 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. UnSend! UnSend!
