After the request for more testers (after a backup) I d/l'ed and compiled 2.5.39. My setup isn't trivial, but should be fine for 2.6; SiS chipset, athlon 1gzH, 512Mem, pci promis ide controler, softraid 0 and 5. This is a gentoo install that loves devfs for some reason (I've always found the paths to be overly long.) Anyway, right after partition detection ide-scsi detection of my old no-brand cdrw drive and dvd drive triped this (written down):" SCSI subsystem driver Revision: 1.0 request_module[scsi_hostadapter]: not ready request_module[scsi_hostadapter]: not ready Sleeping function called from illegal context at /mnt/src/linux-2.4.39/include/asm/semaphore.h:119 ... ...
