Patch tested: 1) I was not able to reproduce the memtester problem with it. So we shall take this patch.
2) But the bus error when building the kernel package are still here. So there is still another issue pending. -- instabilities with highmem activated https://bugs.launchpad.net/bugs/633227 You received this bug notification because you are a member of TI OMAP Developers, which is a direct subscriber. Status in “linux-ti-omap4” package in Ubuntu: New Bug description: Seen on Maverick: 2.6.35-903.9 HW: pandaboard ES2.0 Using following kernel memory allocation (in bootargs): mem=4...@0x80000000 mem=5...@0xa0000000 Instabilities have been observed in 2 different ways: 1) The following memtester test: sudo memtester -p 0xb0000000 120 Fails in few seconds with a "illegal instruction” error. Then various behaviors can be seen: the UI can freeze, shell commands be unavailable. The systems works well again after a reboot. 2) By doing a native build of a kernel package (with file-system on SD card, and kernel sources on an NFS mount): After 15mins to 1h30, a "compiler error: bus error" triggers and the build stops (and the platform hangs). This issue cannot be reproduced if using mem=4...@0x80000000 mem=2...@0xa000000. This issue cannot be reproduced with highmen deactivated from the kernel config. This issue can be reproduced with 'nosmp' in kernel command line. _______________________________________________ Mailing list: https://launchpad.net/~tiomap-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~tiomap-dev More help : https://help.launchpad.net/ListHelp
