From linux-kernel Sat Jan 10 21:23:43 2004 From: Kai Vehmanen Date: Sat, 10 Jan 2004 21:23:43 +0000 To: linux-kernel Subject: 2.4.20- boot freezes; works on 2.4.19 Message-Id: X-MARC-Message: https://marc.info/?l=linux-kernel&m=107377020722155 With kernel 2.4.20 and newer (tested all 2.4 kernels until the new 2.4.24), my machine hangs during the boot sequence, right _after_ local filesystems cheched and _before_ they are succesfully mounted. This happens every time, and always at the same place. 2.4.19 (and earlier, have ran various kernels since 2.2.xx on this machine) have never frozen during boot. I know this sounds crazy, but I've tested dozens of times and the problem occurs systematically each and every time. 2.4.19 otoh has not froze even once. Now what makes this more curious is that if I do a cold-boot (press the reset-button after boot freezes), the second boot goes through fine, and once up, system works like a charm. The freeze-on-boot error only occurs if I do a sw-reboot, or after power-up. When the boot seq freezes, the console still works (I can type "foobar" and see the results), but kernel does not respond to any commands (ctrl-alt-del does not work, neither does SysReq). And no oopses either. As the system is not yet fully up, I cannot gather any other info about the system state. Anyone else seen this problem? Ideas where to start testing? The 2.4.19->2.4.20 patch is quite large (5MB gzipped!), so manually going through all the changesets would take me forever (2 boots per try :(). I haven't yet tested 2.6.
