linux on usb flash drive with suspend problem.

BILLYKANE · 01-22-2012, 12:49 AM

Hello all. I installed chakra linux on one usb flash disk. It works very well except the suspend function.Once I try to suspend (to memory) and resume, it says that the /dev/sda1(/ directory) was write-protected . I try to remount it, but get no lucky. When reboot ,fsck works and fixes some file system errors.

For logical reasoning,I find it is because when suspend, the USB driver( /dev/sda1 ) is power off, and this make file system error occurs, so /dev/sda1 was mounted as read-only.

Anyone know how to fix this problem?

Try pm-utils (pm-suspend) and see if that hooks & unhooks things any smarter. I would also check the suspednd/resume in the logs.

Are you using a live install to usb sort of deal or did you do a real normal install to that flash along with a swap file?

I did a real normal install without swap.However, I tried to acitve my swap patition in my hard disk using swapon.There is also bugs report in launchpad, but no resolution:
