Try "vmalloc=256M". > I had quite a bit of trouble around vmalloc/32bit and XFS, I finally went to 64 bit (vmalloc address space is much bigger--no issues once I went to 64bit) but that does not help you if your hardware is 32bit only, if you pentium can support 64bit and you have a 64bit machine elsewhere compiling a 64bit one there and installing and booting a 64 bit kernel on a full 32-bit userspace is possible (I ran that setup for 6 months on fedora 18) if you want to avoid a 64-bit reinstall in the short term. /proc/meminfo does show basic vmalloc allocation size and usage, so you know what your current size and usage is and can adjust from there, I think the vmalloc space comes out of the 1024M of low memory address space which is the reason for the limit on 32bit. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
