[Bug 633227] Re: instabilities with highmem activated
I tried build 2.6.37 mainline kernel which was just released with the
Ubuntu Natty ti-omap4 kernel config. 2.6.37 kernel boots fine with our
Ubuntu Natty minimal root file system. But I can still reproduce this
issue.
I will post this issue to upstream mail list for more attention.

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.
