Title: instabilities with highmem activated Status in “linux-ti-omap4” package in Ubuntu: Confirmed Status in “linux-ti-omap4” source package in Maverick: Fix Released Status in “linux-ti-omap4” source package in Natty: Confirmed Bug description: Seen on Maverick: 2.6.35-903.9 HW: pandaboard ES2.0 Using following kernel memory allocation (in bootargs): mem=460M@0x80000000 mem=512M@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=460M@0x80000000 mem=256M@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
