Hi,

I thought it was a regression but doing quite intensive tests, I had a problem
with 2.6.30 as well and eventually the system was frozen.

Last syslog messages were:
Jul 29 12:45:10 tangerine kernel: I/O error in filesystem ("sdh4") meta-data
dev sdh4 block 0xae4598       ("xfs_trans_read_buf") error 5 buf count 40

problem(s)
Jul 29 12:45:12 tangerine kernel: XFS: Unable to update superblock counters.
Freespace may not be correct on next mount.
Jul 29 12:45:13 tangerine kernel: hdc: lost interrupt

BTW /dev/hdc is a CDROM drive without a media in it.

Regards

Jean-Luc
