[Virtual-pkg-base-maintainers] Bug#556024: base: Kernel crashes on disk i/o (with PostgreSQL 8.4)

[Steffen Dedekind]

Package: base
Severity: important

While I performing a test with the database postgresql version 8.4 the kernel hangs up:

Call Trace:
journal_dirty_data
ext3_journal_dirty_data
walk_page_buffers
journal_dirty_data_fn
ext3_ordered_write_end
generic_file_buffered_write
ext3_mark_inode_dirty
__generic_file_aio_write_nolock
update_queue
generic_file_aio_write
ext3_file_write
do_sync_write
autoremove_wake_function
.....

I'm using the Debian 5.0.3 lenny with the 2.6.30-2-amd64 kernel (Netinst) on a Dell server.
In the test mentioned above I provide approx. 250 SQL-Inserts to PostgreSQL for performance testing.
The crashtime varies from 20min after the test starts up to 7 hours.
I tried to get help with some PostreSQL support - so we tested several configurations of PostgreSQL without
any success. It semms there is a Disk i/o problem in the kernel.
Contact me if i should provide some more information.

Best regards
Steffen Dedekind
