Package: kernel
Severity: important
Basically I wanted to resize on the fly a reiserfs partition, itself
based on a LVM logical volume.
Here are the steps I followed:
- create a PV with 2 8.5Gigs partitions from 2 different ide disks
- create a LV of 8 Gigs
- mkfs.reiserfs it
- mount it
- lvextend the LV by 2Gigs
- resizefs.reiserfs it, nope if it's not moutntet read-only, so I
remounted it ro (mount -o remout,ro)
- resizefs.reiserfs +2G worked
- mount -o remount,rw and there got the following general protection
fault:
general protection fault: 0000 [1]

- after this I type df, the partition size was updated
- then mount alone, the partition was still ro
- mount -o remout,rw again and there got mount hanged
Hope this helps, find me as gom on #debian-amd64 if needed
