aic7xxx: first mount always fails
The first attempt at mounting a disc in my Traxdata CDR drive after boot always fails. From the second on, everything works flawlessly. Current setup is 2.2.18 kernel + 6.1.11-2.2.18 patch, but I've been experiencing this behaviour since I bought the adapter (around 2.2.12 or so). aic7xxx gets loaded as a module. Here's some diagnostic info from the failed mount. If more is needed, please let me know. (of course, a disc _is_ present in the drive). # modprobe aic7xxx Apr 13 11:20:04 aidi kernel: ahc_pci:0:12:0: Host Adapter Bios disabled.

Personally I'd be happy with the quick hack, but the slice-enhanced naming scheme possible with devfs looks like the way to go. Besides, I think that documenting this issue in the "Changes" file would help somehow.

Partition renumbering under 2.4.0
Hi, I've noticed that some logical partitions get different numbering under 2.2.16 and 2.4.0. Here's my /dev/hdb layout: hdb1: fat32 hdb2: Solaris partition (contains 4 Solaris slices) hdb3: ext2 hdb4: extended partition (contains 1 ext2 logical partition) and here's how it gets detected by the kernels: 2.2.16: hdb: hdb1 hdb2 hdb3 hdb4 < hdb9 > 2.4.0: hdb: hdb1 hdb2 hdb3 hdb4 < hdb5 > hdb2: Note that the ext2 logical partition is called "hdb9" by 2.2.16 and "hdb5" by 2.4.0. This makes it difficult to manage multi-boot systems with 2.2.x and 2.4.x kernels, as it requires updating fstab between boots. Switching to other identification strategies such as ext2 labels - as discussed in other threads - could be a workaround, as far as I know.

It It's not a fault of dd, or of the read() system call, either. It's just the way /dev/random works - you can't read more bytes than those available in the entropy pool. And if you try, you'll just fail with no error.
