I have a bug report for the first time about reiser4 in 2.6.14-rc1-mm1
with 4k stacks,
preempt and smp. It is the first time I face a bug after using reiser4
for about a year. Well I had to with 4k stacks right ?
firefox has triggerred the bug twice and I had to fsck the filesystem
with --fix --build-fs which fixed the error. After fixing it any
attempt to access the drive resulted in a 'Bus error' message. A sync
and reboot using the sysreq mechanism returned me to a working system.
Sorry if this is not the place to report the bug, or if doesn't get
attatched to the reiser4 thread, I am new to LKML. Thanks in advance.
