[1.] One line summary of the problem: raid0_make_request bug in kernel 2.6.0-test5-bk10
[2.] Full description of the problem/report: Since I updated to the 2.6.0-test5-bk10 kernel I get these bug messages everytime the computer executes a binary file in one of my raid0/lvm partitions (see below how my harddisk is partitioned) for the first time since bootup:
raid0_make_request bug: can't convert block across chunks or bigger
than 4k 286485088 64 The second last number in the bug message differs with every message I get. The last one is either 8, 12, 20, 24 or 64 (and maybe some more which I didn't see). The numbers of messages I get also differs with every exutable. Naturally I get a lot of these messages at boot time from the point onward that init is started. With the 2.6.0-test5-bk3 kernel this problem didn't occur. Despite the fact that these messages are quite annoying they don't seem to have any effect on the work flow. Everything seems to work fine.
